Question

Mark left 3/8 of pizza in the refrigerator. On friday he ate 1/2 if what is left of the pizza. What fraction of the entire pizza did he eat on friday?

Answer 1

3/16 because 3/8 is equal to 6/16 and half of that is 3/16.

Answer 2

Answer:

Mike ate $\frac{3x}{16}$th portion of the pizza on Friday.

Step-by-step explanation:

Let us consider the quantity of pizza = x  

If Mike left $\frac{3x}{8}$ of the pizza in the refrigerator.

On Friday he ate $\frac{1}{2}$ the portion of pizza he ate = $\frac{3x}{8}\times \frac{1}{2}$

= $\frac{3x}{16}$

Therefore, Mike ate $\frac{3x}{16}$th portion of the pizza on Friday.
