Question

A pack of sugar costs £1.25 for 500g. How much for 1kg?

Answer 1

2.5

Explanation:

Change 500g into kg

500g=500/1000kg

=0.5kg

If 0.5kg cost 1.25

what about 1kg

= (1*1.25)/0.5

= 1.25/0.5

=2.5

Answer 2

2.50 £

Explanation:

A pack of sugar costs £1.25 for 500g. How much for 1kg?

500g = 1/2Kg or 0.5 Kg

so 1.25£ is 0.5Kg (1/2)

1.25 * 2 = 2.50£ is your answer
