Answer 1

Answer: 12

Explanation:

2/3 = 8/12

1/4 = 3/12

8/12 + 3/12 + 11/12

amy & anna ate 11 and david had 1

Answer 2

There were 12 donuts in the box.

Explanation:

We are given the following information in the question:

Let x be the number of donuts in the box.

Then, according to the question

Number of donuts eaten by Amy =
`(2x)/(3)`

Number of donuts eaten by Anna =
`(x)/(4)`

Number of donuts eaten by David = 1

Total number of donuts =

Number of donuts eaten by Amy + Number of donuts eaten by Anna + Number of donuts eaten by David

`\Rightarrow (2x)/(3) + (x)/(4) + 1 = x`

Solving the above equation:

`11x + 12 = 12x\\x =12`

Thus, there were 12 donuts in the box.
