Very Short Answer Type Questions

Question 1. What is the difference between scale and iron rods used at shops of cloth by shopkeeper?
Answer: A scale has clear markings for every centimeter. However, the iron rods used by shopkeepers to measure cloth have very few or no marks. The scale gives a precise measurement, while the iron rod is less accurate and might be used for quick, approximate measurements.
In simple words: A regular scale has lines for every centimeter, but the iron stick cloth sellers use has very few or no measurement lines.

🎯 Exam Tip: Focus on precision when describing differences in measuring tools. Mentioning the presence or absence of markings is key here.

Question 2. What is the difference between meter scale and inch tape used by tailor?
Answer: A meter scale is a rigid, straight measuring tool, typically one meter long, that cannot be folded. It usually has marks for inches, centimeters, and millimeters. An inch tape, used by tailors, is a flexible measuring tape that can be rolled up and is much longer than a meter scale, making it suitable for measuring curved surfaces or around objects.
In simple words: A meter scale is straight and cannot bend, but an inch tape is flexible and longer, so tailors can wrap it around things to measure.

🎯 Exam Tip: Highlight the key properties: meter scales are rigid and fixed length, while inch tapes are flexible and longer, suited for different measurement needs.

Question 4. One end of a mate is 200 cm and second end is 100 cm. Represent these in meter.
Answer: To convert centimeters to meters, we divide the number of centimeters by 100. So, 200 cm becomes \( \frac{200}{100} \) meters, which is 2 meters. Similarly, 100 cm becomes \( \frac{100}{100} \) meters, which is 1 meter. Therefore, one end is 2 meters and the second end is 1 meter.
In simple words: To change centimeters to meters, you divide by 100. So, 200 cm is 2 meters, and 100 cm is 1 meter.

🎯 Exam Tip: Always remember the conversion factor: 1 meter = 100 cm. Dividing by 100 is the correct operation when converting from centimeters to meters.

Question 5. In a long jump Rafiq jumped 1 meter 78 cm. Write it in centimeter.
Answer: To convert 1 meter 78 cm into centimeters, we first convert the meters to centimeters. Since 1 meter equals 100 centimeters, 1 meter is 100 cm. Then, we add the remaining 78 cm. So, 100 cm + 78 cm = 178 cm. Rafiq jumped a total of 178 centimeters.
In simple words: We know 1 meter is 100 cm. So, 1 meter and 78 cm together make 100 plus 78, which is 178 cm.

🎯 Exam Tip: When converting mixed units to a smaller single unit, convert the larger unit first, then add the smaller unit. Here, meters to cm, then add cm.

Question 6. Write the given measurements in cm.
(i) 1 meter 40 cm.
(ii) 1 meter 70 cm.
(iii) 1 meter 30 cm.
Answer: To convert these measurements into centimeters, we use the fact that 1 meter = 100 cm. We convert the meter part and then add the existing centimeters.
(i) 1 meter 40 cm = 100 cm + 40 cm = 140 cm.
(ii) 1 meter 70 cm = 100 cm + 70 cm = 170 cm.
(iii) 1 meter 30 cm = 100 cm + 30 cm = 130 cm.
In simple words: For each measurement, change the meter part to 100 cm, then add the other centimeters to get the total in centimeters.

🎯 Exam Tip: Remember the basic conversion that 1 meter is 100 centimeters. This makes adding the remaining centimeters straightforward for finding the total length.

Question 7. Write the given measurements in meter cm.
(i) 900 cm.
(ii) 560 cm
(iii) 240 cm.
Answer: To convert centimeters into meters and centimeters, we divide the total centimeters by 100. The quotient gives the number of meters, and the remainder gives the number of centimeters.
(i) 900 cm = 900 ÷ 100 = 9 meters and 0 cm (simply 9 meters).
(ii) 560 cm = 500 cm + 60 cm = 5 meters 60 cm.
(iii) 240 cm = 200 cm + 40 cm = 2 meters 40 cm.
In simple words: To change centimeters into meters and centimeters, take out groups of 100 cm. Each group of 100 cm is 1 meter. The leftover centimeters stay as they are.

🎯 Exam Tip: When converting centimeters to meters and centimeters, think of how many hundreds are in the number. That gives you the meters, and the rest are centimeters.

Conversion Of Meter Into Centimeter

Question 2. Convert 4 centimeter into millimeter.
Answer: To convert centimeters to millimeters, we use the conversion factor that 1 centimeter = 10 millimeters. Therefore, to find out how many millimeters are in 4 centimeters, we multiply 4 by 10. So, 4 centimeters = 4 x 10 millimeters = 40 millimeters.
In simple words: Since 1 centimeter is equal to 10 millimeters, 4 centimeters will be 4 times 10, which makes 40 millimeters.

🎯 Exam Tip: Remember the basic conversion: 1 cm = 10 mm. This is a common conversion used in various measurement problems.

Question 3. Convert 5 kilometer into meter.
Answer: To convert kilometers to meters, we use the conversion factor that 1 kilometer = 1000 meters. So, to find out how many meters are in 5 kilometers, we multiply 5 by 1000. Therefore, 5 kilometers = 5 x 1000 meters = 5000 meters.
In simple words: Since 1 kilometer is 1000 meters, 5 kilometers means you multiply 5 by 1000, which gives 5000 meters.

🎯 Exam Tip: Always remember that "kilo" means 1000. So, 1 kilometer is 1000 meters, and this simple rule applies to all kilo-unit conversions.

Question 4. How many meters are there in 8 kilometers?
Answer: We know that 1 kilometer is equal to 1000 meters. So, to find the number of meters in 8 kilometers, we multiply 8 by 1000. This gives us 8 x 1000 meters = 8000 meters. Therefore, there are 8000 meters in 8 kilometers.
In simple words: If 1 kilometer is 1000 meters, then 8 kilometers will be 8 times 1000 meters, which is 8000 meters.

🎯 Exam Tip: Practice these direct multiplication conversions (kilometers to meters) often to make them second nature in tests.

Question 5. Convert \( \frac{1}{2} \) kilometer into meters.
Answer: We know that 1 kilometer is equal to 1000 meters. To convert \( \frac{1}{2} \) kilometer into meters, we multiply \( \frac{1}{2} \) by 1000. So, \( \frac{1}{2} \times 1000 = 500 \) meters. Therefore, \( \frac{1}{2} \) kilometer is 500 meters.
In simple words: Since 1 kilometer is 1000 meters, half a kilometer will be half of 1000, which is 500 meters.

🎯 Exam Tip: Remember that fractions like \( \frac{1}{2} \) are simply parts of a whole. To find a fraction of a measurement, multiply the fraction by the total conversion value.

Question 6. How many centimeters are there in \( \frac{1}{4} \) meter?
Answer: We know that 1 meter is equal to 100 centimeters. To find out how many centimeters are in \( \frac{1}{4} \) meter, we multiply \( \frac{1}{4} \) by 100. So, \( \frac{1}{4} \times 100 = 25 \) centimeters. This means \( \frac{1}{4} \) of a meter is 25 centimeters.
In simple words: Since there are 100 centimeters in 1 meter, one-fourth of a meter is 25 centimeters.

🎯 Exam Tip: When dealing with fractions of units, multiply the fraction by the known conversion factor. For example, half a meter is 0.5 * 100 cm = 50 cm.

Question 7. What is the difference between meter scale and rod?
Answer: A meter scale is a precise tool for measuring length, marked with inches, centimeters, and millimeters. It is considered an authentic way to measure. A rod, on the other hand, is generally made to a specific length based on a meter scale but does not have detailed centimeter or millimeter markings. Rods are often used for general length comparisons rather than precise measurements.
In simple words: A meter scale has small marks for inches, cm, and mm, which makes it good for exact measuring. A rod is just a certain length without those small marks.

🎯 Exam Tip: When distinguishing tools, focus on their key features like markings (for precision) and intended use. Precision is a main difference here.

Question 8. What is the difference between meter scale and inch tape?
Answer: A meter scale is usually a rigid, straight measuring tool, fixed at 1 meter in length, which cannot be folded. An inch tape, however, is a flexible measuring tool that is typically much longer than 1 meter and can be easily folded or rolled up. It is useful for measuring around curves or uneven surfaces, which a rigid meter scale cannot do.
In simple words: A meter scale is stiff and 1 meter long, you can't fold it. An inch tape is soft, longer, and can be folded, making it good for measuring curved things.

🎯 Exam Tip: Understand that the choice between a meter scale and an inch tape depends on what you need to measure: straight lines versus curved or longer lengths.
