Answer 1

31.25 kg of flour is needed to make 50 cakes

Explanation:

A 2.5-kg bag of flour contains enough flour to make 4 cakes. a) How much flour is needed to make 50 cakes?

We can find it by using unitary method i.e first find quantity of flour needed for 1 cake and then we can find quantity of flour needed for 50 cakes.

Flour needed to make 4 cakes = 2.5 kg

Flour needed to make 1 cake =
`(2.5)/(4)` kg

Flour needed to make 50 cakes =
`(2.5)/(4)* 50`

= 31.25 kg

So, 31.25 kg of flour is needed to make 50 cakes
