Question

David brought a variety pack of delicious donuts for his daughters Amy & Anna. Amy ate 2/3 of the pack and Anna devoured 1/4 of them. Finally David ate the remaining one donut. Find out the total number of donuts in the pack.

Answer 1

Amy:8

Anna:3

Explanation:

Answer 2

12

Explanation:

Let the total number of donuts in the pack be x.

Amy = 2/3x

Anna = 1/4x

David = 1

x - 2/3x - 1/4x = 1

Find common denominators for 2/3 and 1/4

The common denominator is 12

2/3 * 4/4 = 8/12

1/4 * 3/3 = 3/12

x - 8/12x - 3/12x = 1

x - 11/12x = 1

1/12x = 1

x = 12

You can always check

Amy = 8

Anna = 3

So David must equal to 1

Hope this helps :)

Have an awesome day!
