=================================================

How to get these answers

She uses 1/3 of a cup for 1 cake, so we have this ratio

1/3 cup : 1 cake

Multiply both sides by 3 and we end up with

1 cup : 3 cakes

Then multiply both sides by 4 to change "1 cup" to "4 cups" and we have

4 cups : 12 cakes which is the answer to the first part

-------------

For part 2, we'll follow the same steps as before, but instead of multiplying both sides by 4, we do 2 instead because we're dealing with 2 cups of oil.

1/3 cup : 1 cake

3*(1/3 cup) : 3*(1 cake)

1 cup : 3 cakes

2*(1 cup) : 2*(3 cakes)

2 cups : 6 cakes which is the answer to the second part

Number of cake made from 2 and 4 cup of oil 6 cakes and 12 cakes

Given that;

Cup used for each cake = 1/3 cup

Find:

Number of cake made from 4 cup of oil

Number of cake made from 2 cup of oil

Computation:

Number of cake made from 4 cup of oil = 4 / (1/3)

Number of cake made from 4 cup of oil = 4 / (0.334)

Number of cake made from 4 cup of oil = 12 cakes

Number of cake made from 2 cup of oil = 2 / (1/3)

Number of cake made from 2 cup of oil = 2 / (0.334)

Number of cake made from 2 cup of oil = 6 cakes
