CBSE Class 4 Maths Measurement Worksheet Set 05

I. Fill in the blanks.

Question 1. 1 litre can fill 2 bottles of ____________ ml each.
Answer: 500
In simple words: Since 1 litre = 1000 ml, dividing it equally into 2 bottles gives 500 ml each.

Exam Tip: Remember the conversion 1 litre = 1000 ml to solve capacity problems quickly.

Question 2. Standard unit of mass is ____________________________.
Answer: kilogram (or kg)
In simple words: The standard unit used to measure heavy objects is the kilogram.

Exam Tip: Memorize standard metric units for length (metre), mass (gram/kilogram), and capacity (litre).

Question 3. Four ___________ g make kg.
Answer: 250
In simple words: Since 1 kg = 1000 g, four 250 g weights make 1000 g (1 kg).

Exam Tip: Think of standard weights: \(4 \times 250 = 1000\).

Question 4. ____________ kilometre is 500 metre.
Answer: \(\frac{1}{2}\) (or 0.5)
In simple words: 500 metres is half of 1000 metres, which is half a kilometre.

Exam Tip: \(1 \text{ km} = 1000 \text{ m}\), so half of 1000 is 500.

Question 5. Ten 100 ml make ___________ litre.
Answer: 1
In simple words: Ten times 100 ml equals 1000 ml, which is 1 litre.

Exam Tip: \(10 \times 100 = 1000 \text{ ml} = 1 \text{ litre}\).

Question 6. \(\frac{3}{4} \text{ kg} =\) ___________ g
Answer: 750
In simple words: Since 1 kg = 1000 g, multiply 1000 by \(\frac{3}{4}\) to get 750 g.

Exam Tip: \(\frac{3}{4}\) of 1000 is \(3 \times 250 = 750\).

Question 7. Standard unit of ________________________ is Litre.
Answer: capacity (or volume)
In simple words: Litre is the standard metric unit used to measure liquids.

Exam Tip: Capacity measures how much container can hold.

Question 8. __________________ 200 ml make 1 litre..
Answer: Five
In simple words: Five bottles of 200 ml add up to 1000 ml (1 litre).

Question 9. 250 g = ___________ kg
Answer: \(\frac{1}{4}\) (or 0.25)
In simple words: To convert grams to kilograms, divide by 1000: \(250 \div 1000 = \frac{1}{4} \text{ kg}\).

Exam Tip: Smaller unit to larger unit means division.

Question 10. 50 cm = ___________ metre.
Answer: \(\frac{1}{2}\) (or 0.5)
In simple words: 50 cm is half of 100 cm, which is \(\frac{1}{2}\) metre.

Exam Tip: \(1 \text{ m} = 100 \text{ cm}\).

II. Draw the line segments of the following lengths.

Question 1. a) 6 cm
Answer:
1. Place a ruler on a paper.
2. Mark a point at 0 cm and another point at 6 cm.
3. Join the two points with a straight line.

Exam Tip: Always start measuring accurately from the 0 mark on your ruler, not the edge of the plastic scale.

Question 2. b) \(7\frac{1}{2} \text{ cm}\)
Answer:
1. Place the ruler on paper.
2. Mark a point at 0 cm and another at 7 cm and 5 small divisions (\(7.5 \text{ cm}\)).
3. Draw a straight line connecting both points.

Exam Tip: \(\frac{1}{2} \text{ cm}\) corresponds to the longer tick mark exactly halfway between 7 cm and 8 cm.

III. 1. Express in cm ( centimetres )

Question 1. a) 8 m 30 cm
Answer:
\(1 \text{ m} = 100 \text{ cm}\)
\(8 \text{ m} = 8 \times 100 = 800 \text{ cm}\)
\(800 \text{ cm} + 30 \text{ cm} = 830 \text{ cm}\)
In simple words: Convert metres to centimetres by multiplying by 100, then add the remaining centimetres.

Exam Tip: Combine meters and centimeters by simply putting the meter value in the hundreds place.

Question 2. b) 2 m 1 cm
Answer:
\(1 \text{ m} = 100 \text{ cm}\)
\(2 \text{ m} = 2 \times 100 = 200 \text{ cm}\)
\(200 \text{ cm} + 1 \text{ cm} = 201 \text{ cm}\)
In simple words: 2 metres is 200 cm, plus 1 cm gives 201 cm.

Exam Tip: Be careful with single-digit centimeters; write 1 cm as 01 cm.

2. Express in m ( metres )

Question 1. a) 303 cm
Answer:
\(100 \text{ cm} = 1 \text{ m}\)
\(303 \text{ cm} = 300 \text{ cm} + 3 \text{ cm} = 3 \text{ m} 3 \text{ cm}\)
In simple words: Split the hundreds to make metres and keep the remainder as centimetres.

Exam Tip: The last two digits represent centimetres, and the remaining digits represent metres.

Question 2. b) 675 cm
Answer:
\(675 \text{ cm} = 600 \text{ cm} + 75 \text{ cm} = 6 \text{ m} 75 \text{ cm}\)
In simple words: 600 cm makes 6 metres, leaving 75 cm.

Exam Tip: Separate hundreds into metres directly.

IV. Answer the following.

Question 1. 7250 m = ________________________ km
Answer: 7 km 250 m (or 7.250 km)
In simple words: Divide by 1000 since \(1 \text{ km} = 1000 \text{ m}\).

Exam Tip: The thousands digit gives kilometers, and the rest gives meters.

Question 2. \(5\frac{1}{4} \text{ km} =\) ________________________ m
Answer: 5250
In simple words: \(5 \text{ km} = 5000 \text{ m}\), and \(\frac{1}{4} \text{ km} = 250 \text{ m}\), total = 5250 m.

Exam Tip: Remember \(\frac{1}{4} \text{ km} = 250 \text{ m}\), \(\frac{1}{2} \text{ km} = 500 \text{ m}\), and \(\frac{3}{4} \text{ km} = 750 \text{ m}\).

Question 3. 4540 m = ________________________ km ________________________ m
Answer: 4 km 40 m
In simple words: 4000 m is 4 km, plus 540 m.

Exam Tip: Split into thousands and remainder.

Question 4. 3 km 650 m = ________________________ m
Answer: 3650
In simple words: Multiply 3 by 1000 and add 650 m.

Question 5. 8500 g = ________________________ kg
Answer: 8 kg 500 g (or 8.5 kg)
In simple words: Divide 8500 by 1000 to get kilograms and grams.
Exam Tip: 1000 g = 1 kg.

Question 6. 1250 g = ________________________ kg
Answer: 1 kg 250 g (or 1.25 kg)
In simple words: 1000 g makes 1 kg, leaving 250 g.

Exam Tip: Separate the thousands place for kilograms.

Question 7. \(7\frac{3}{4} \text{ kg} =\) ________________________ g
Answer: 7750
In simple words: \(7 \text{ kg} = 7000 \text{ g}\), and \(\frac{3}{4} \text{ kg} = 750 \text{ g}\), giving 7750 g.

Exam Tip: \(\frac{3}{4}\) of 1000 is 750.

Question 8. \(10\frac{1}{2} \text{ kg} =\) ________________________ g
Answer: 10500
In simple words: \(10 \text{ kg} = 10000 \text{ g}\), plus 500 g equals 10500 g.

Exam Tip: Half a kilogram is always 500 g.

Question 9. 6750 ml = ________________________ l
Answer: 6 l 750 ml (or 6.75 l)
In simple words: Since \(1 \text{ l} = 1000 \text{ ml}\), divide by 1000.

Exam Tip: Three decimal places for millilitres to litres.

Question 10. 2500 ml = ________________________ l
Answer: 2 l 500 ml (or 2.5 l)
In simple words: 2000 ml is 2 litres, plus 500 ml.

Exam Tip: 500 ml is half a litre.

Question 11. 3 litre 150 ml = ________________________ ml
Answer: 3150
In simple words: 3 litres = 3000 ml, plus 150 ml = 3150 ml.

Exam Tip: Convert litres to millilitres by multiplying by 1000.

Question 12. \(9\frac{3}{4} \text{ litres} =\) ________________________ ml
Answer: 9750
In simple words: \(9 \text{ l} = 9000 \text{ ml}\) and \(\frac{3}{4} \text{ l} = 750 \text{ ml}\), total is 9750 ml.
Exam Tip: \(\frac{3}{4} \text{ l} = 750 \text{ ml}\).

V. Answer the following

Question 1. 1 kg of apples cost Rs. 80. What is the cost of 500 g ?
Answer:
Cost of 1 kg (1000 g) of apples = Rs. 80
Cost of 500 g (which is half of 1 kg) = \(80 \div 2 = \text{Rs. } 40\)
In simple words: Since 500 g is half of 1 kg, the cost will also be half of Rs. 80, which is Rs. 40.
Exam Tip: Always convert quantities to the same units before finding the unitary method solution.

Question 2. You have a jug that holds 3 litres of orange juice. How many glasses of capacity 250 ml each can you fill ?
Answer:
Total capacity of jug = 3 litres = \(3 \times 1000 = 3000 \text{ ml}\)
Capacity of 1 glass = 250 ml
Number of glasses filled = \(3000 \div 250 = 12 \text{ glasses}\)
In simple words: Convert litres to millilitres first, then divide by the capacity of one glass.
Exam Tip: Since 4 glasses of 250 ml make 1 litre, for 3 litres you need \(3 \times 4 = 12\) glasses.

Question 3. Sahil jogged 2 times around a park that had a path of length 750 m. How many km did she jog ?
Answer:
Length of 1 round around the park = 750 m
Number of rounds jogged = 2
Total distance in metres = \(750 \times 2 = 1500 \text{ m}\)
Converting metres to kilometres: \(1500 \text{ m} = 1 \text{ km} 500 \text{ m} = 1.5 \text{ km}\)
In simple words: Multiply the path length by 2 to get total metres, then convert to kilometres by dividing by 1000.
