Question

A 50g piece of chocolate costs 45p. How much would 1kg of chocolate cost at this rate?

Answer 1

Step-by-step explanation:

Cost of 50g of chocolate= 45 p

cost of 1 g of chocolate = 45/50 p. = 0.9p

cost of 1kg = 1000g = 0.9* 1000 p

= 900 p

Answer 2

1kg = 1000g

1000/50 = 20

So 1kg of chocolate equals 20 lots of 50g chocolate

One 50g chocolate is 45p

45p*20=900p

1kg would cost 900p
