Question

6 identical toys weigh 1.8kg. a) convert 1.8kg to grams. b) what is the weight of one toy? Give your answer in grams. c) how much would 4 toys weigh? Give your answer in kilograms

Answer 1

a. 1.8kg to grams

1000g =1kg

x =1.8kg

cross multiply

x = 1.8 x 1000

x= 1800g

b. weight of one toy

6 toys = 1800g

1 toy = 1800÷6

1 toy = 300g

c. 1kg = 300g

4toys = x

x = 4 x 300

x = 1200g

1200g to kilogram

1000g = 1kg

1200g = x

cross multiply

1000x = 1200

x = 1200÷1000

x = 1.2kg

Answer 2
