Question

300g of bananas cost £1.80. how much does 1kg cost?

Answer 1

Answer:

£6

Step-by-step explanation:

300 g = .3 kg

We can use ratios to solve

.3 kg             1 kg

------------- = -----------

1.8                     x

Using cross products

.3x = 1 * 1.8

.3x = 1.8

Divide each side by .3

.3x/.3 = 1.8/.3

x =6

Answer 2

Maybe try dividing by 300 and timesing by 1000?
