d) \(400\text{ cm}\)
e) \(613\text{ cm}\)
f) \(310\text{ cm}\)
Answer:
To convert cm to m, divide by 100.
a) \(100\text{ cm} = \frac{100}{100} = 1\text{ m}\)
b) \(250\text{ cm} = 2\text{ m } 50\text{ cm} = 2.5\text{ m}\)
c) \(720\text{ cm} = 7\text{ m } 20\text{ cm} = 7.2\text{ m}\)
d) \(400\text{ cm} = \frac{400}{100} = 4\text{ m}\)
e) \(613\text{ cm} = 6\text{ m } 13\text{ cm} = 6.13\text{ m}\)

f) \(10\text{m } 50\text{cm}\)
Answer:
To convert metres to cm, multiply the metre part by 100 and add the cm part.
a) \(5 \times 100 + 50 = 500 + 50 = 550\text{ cm}\)
b) \(6 \times 100 + 18 = 600 + 18 = 618\text{ cm}\)
c) \(9 \times 100 = 900\text{ cm}\)
d) \(4 \times 100 + 25 = 400 + 25 = 425\text{ cm}\)
e) \(7 \times 100 + 3 = 700 + 3 = 703\text{ cm}\)
f) \(10 \times 100 + 50 = 1000 + 50 = 1050\text{ cm}\)
In simple words: Multiply metres by 100 and add centimetres.

Exam Tip: Watch out for single-digit centimetres like 3 cm, which becomes 03 cm (\(703\text{ cm}\), not \(73\text{ cm}\)).

Question 4. Express in km

b) \(3072\text{m}\)
c) \(1961\text{m}\)
d) \(8406\text{m}\)
e) \(5500\text{m}\)
f) \(9000\text{m}\)
Answer:
To convert metres to kilometres, divide by 1000 (thousands digit becomes km, remaining is m).
a) \(4652\text{ m} = 4\text{ km } 652\text{ m}\)
b) \(3072\text{ m} = 3\text{ km } 72\text{ m}\)
c) \(1961\text{ m} = 1\text{ km } 961\text{ m}\)
d) \(8406\text{ m} = 8\text{ km } 406\text{ m}\)
e) \(5500\text{ m} = 5\text{ km } 500\text{ m}\)
f) \(9000\text{ m} = 9\text{ km}\)
In simple words: The first digit represents kilometres and the last three digits represent metres.

Exam Tip: Always ensure there are three digits in the metre part by padding with zeros if necessary.

Question 5. Express in m

Answer:
To convert kilometres to metres, multiply by 1000.
a) \(2 \times 1000 = 2000\text{ m}\)
b) \(6\frac{1}{2}\text{ km} = 6 \times 1000 + 500 = 6500\text{ m}\)
c) \(7 \times 1000 = 7000\text{ m}\)
d) \(3\frac{1}{2}\text{ km} = 3 \times 1000 + 500 = 3500\text{ m}\)
e) \(8\frac{1}{2}\text{ km} = 8 \times 1000 + 500 = 8500\text{ m}\)
f) \(5 \times 1000 = 5000\text{ m}\)
In simple words: Multiply the number of kilometres by 1000; a half kilometre adds 500 metres.

Exam Tip: \(\frac{1}{2}\text{ km}\) is always equal to \(500\text{ m}\).

Question 6. Meenu walked \(640\text{m}\) from her house to her school and back again. What distance did she walk in all?
Answer:
Distance from house to school = \(640\text{ m}\)
Distance from school back to house = \(640\text{ m}\)
Total distance walked = \(640\text{ m} + 640\text{ m} = 1280\text{ m}\) (or \(1\text{ km } 280\text{ m}\))
In simple words: Add the going distance and the return distance together.

Exam Tip: "Back again" means she covered the same distance twice.

Question 7. Raju cycled 10 times around a garden that had a path of length \(300\text{m}\). How many km he cycled?
Answer:
Length of one round = \(300\text{ m}\)
Number of rounds = 10
Total distance in metres = \(300\text{ m} \times 10 = 3000\text{ m}\)
Converting to kilometres: \(3000\text{ m} \div 1000 = 3\text{ km}\)
In simple words: Multiply one lap distance by the number of laps, then convert metres to kilometres.

Exam Tip: To convert metres to kilometres, divide by 1000.

d) \(2500\text{ ml}\)
e) \(5370\text{ ml}\)
f) \(7000\text{ ml}\)
Answer:
To convert millilitres to litres, divide by 1000.
a) \(2000\text{ ml} = 2\text{ l}\)
b) \(2450\text{ ml} = 2\text{ l } 450\text{ ml} = 2.45\text{ l}\)
c) \(1040\text{ ml} = 1\text{ l } 40\text{ ml} = 1.04\text{ l}\)
d) \(2500\text{ ml} = 2\text{ l } 500\text{ ml} = 2.5\text{ l}\)
e) \(5370\text{ ml} = 5\text{ l } 370\text{ ml} = 5.37\text{ l}\)
f) \(7000\text{ ml} = 7\text{ l}\)
In simple words: The thousands digit gives the number of litres, and the rest is millilitres.

Exam Tip: Place a decimal point after three digits from the right to convert ml to litres.

Question 9. Express in millilitres

b) \(3 \times 1000 = 3000\text{ ml}\)
c) \(5\frac{1}{4}\text{ l} = 5 \times 1000 + 250 = 5250\text{ ml}\)
d) \(9\frac{1}{2}\text{ l} = 9 \times 1000 + 500 = 9500\text{ ml}\)
e) \(12 \times 1000 = 12000\text{ ml}\)
f) \(7\frac{1}{2}\text{ l} = 7 \times 1000 + 500 = 7500\text{ ml}\)
In simple words: Multiply litres by 1000. Remember \(\frac{1}{4}\text{ l} = 250\text{ ml}\) and \(\frac{1}{2}\text{ l} = 500\text{ ml}\).

Exam Tip: Add three zeros to whole litres when converting to millilitres.

Question 10.
a) How many ml in two spoon fuls of medicine that hold \(5\text{ml}\) each?
Answer:
Quantity in one spoon = \(5\text{ ml}\)
Number of spoons = 2
Total medicine = \(2 \times 5\text{ ml} = 10\text{ ml}\)
In simple words: Multiply the volume of one spoon by 2.

b) Three large mugs of soup, each holding \(1\frac{1}{2}\text{ l}\) is poured into a bowl. How much soup is poured into the bowl?
Answer:
Volume of one mug = \(1\frac{1}{2}\text{ l} = 1.5\text{ l}\)
Number of mugs = 3
Total soup = \(3 \times 1.5\text{ l} = 4.5\text{ l}\) (or \(4\text{ l } 500\text{ ml}\))
In simple words: Multiply 1.5 litres by 3.

c) One glass of water holds \(200\text{ml}\) .How many ml in 6 such glasses?
Answer:
Volume of one glass = \(200\text{ ml}\)
Number of glasses = 6
Total volume = \(6 \times 200\text{ ml} = 1200\text{ ml}\) (or \(1\text{ l } 200\text{ ml}\))
In simple words: Multiply 200 ml by 6.

Exam Tip: Read word problems carefully to determine whether to multiply or divide.

Answer:
To convert kilograms to grams, multiply by 1000.
a) \(6 \times 1000 = 6000\text{ g}\)
b) \(1\frac{3}{4}\text{ kg} = 1 \times 1000 + 750 = 1750\text{ g}\)
c) \(5\frac{1}{4}\text{ kg} = 5 \times 1000 + 250 = 5250\text{ g}\)
d) \(3\frac{1}{2}\text{ kg} = 3 \times 1000 + 500 = 3500\text{ g}\)

f) \(4\frac{1}{2}\text{ kg} = 4 \times 1000 + 500 = 4500\text{ g}\)
In simple words: Multiply kilograms by 1000 and add standard fractional values (\(\frac{1}{4}\text{ kg} = 250\text{ g}\), \(\frac{1}{2}\text{ kg} = 500\text{ g}\), \(\frac{3}{4}\text{ kg} = 750\text{ g}\)).

Exam Tip: Memorize the gram equivalents of common fractions of a kilogram.

Question 13. Mrs Khan is making vegetable salad. She uses \(1\text{kg}\) cucumber, \(\frac{1}{2}\text{kg}\) cabbage, \(1\text{kg}\) carrot and \(\frac{1}{2}\text{kg}\) tomato. What is the weight of the fruit salad?
Answer:
Weight of cucumber = \(1\text{ kg}\)
Weight of cabbage = \(\frac{1}{2}\text{ kg} = 0.5\text{ kg}\)
Weight of carrot = \(1\text{ kg}\)
Weight of tomato = \(\frac{1}{2}\text{ kg} = 0.5\text{ kg}\)
Total weight = \(1 + 0.5 + 1 + 0.5 = 3\text{ kg}\)
In simple words: Add all the individual weights together: \(1 + \frac{1}{2} + 1 + \frac{1}{2} = 3\text{ kg}\).

Exam Tip: Combine like fractions first (\(\frac{1}{2} + \frac{1}{2} = 1\)) to make addition easier.

Question 14. You have a packet of cornflour that weights \(250\text{g}\). How many such packets would you need to make \(1\text{kg}\)?
Answer:
Total weight required = \(1\text{ kg} = 1000\text{ g}\)
Weight of one packet = \(250\text{ g}\)
Number of packets needed = \(1000\text{ g} \div 250\text{ g} = 4\text{ packets}\)
In simple words: Since 250 g is one-fourth of 1000 g, you need 4 packets.

Exam Tip: Always ensure both quantities are in the same unit (\(\text{g}\)) before dividing.

Question 15. If Afnan gains \(6\text{ kg}\), he will be \(50\text{kg}\). What is his weight now?
Answer:
Future weight = \(50\text{ kg}\)
Weight to be gained = \(6\text{ kg}\)
Current weight = \(50\text{ kg} - 6\text{ kg} = 44\text{ kg}\)
In simple words: Subtract the weight he will gain from his future target weight.

Exam Tip: Read carefully: "he will be 50 kg" implies subtraction to find his current weight.
