5+4+1 = 10. If you have 4 nickels out of 10 coins, it means there is a 4/10 chance of selecting one, but to simplify, 2 is the greatest common factor, so you would divide each number.

4/2 = 2.

10/2 = 5.

The answer is 2/5.

First answer: 12

Second answer: 6

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

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
