Question

Tom ate 1/2 of the leftovers. How much pie in all did he eat

Answer 1

1/2+1/2=2/2=1 so 1/2 was eaten and the other half was leftovers.

Answer 2

Answer:  $\dfrac{1}{2}=50\%$ of pie he eat in all.

Step-by-step explanation:

Since we have given that

Let the total pie is represented by 1.

Part of pie of left over is eaten by Tom is given by $\dfrac{1}{2}$

We need to find the part of  left over.

Part of left over would be

$1-\dfrac{1}{2}\\\\=\dfrac{2-1}{2}\\\\=\dfrac{1}{2}$

Hence, $\dfrac{1}{2}=50\%$ of pie he eat in all.
