Question

Alex ordered one pizza. He ate $\frac{1}{3}$ of the pizza and gave $\frac{1}{5}$ of it to his friend.

How much pizza is left?

• A. $\frac{7}{15}$
• B. $\frac{8}{15}$
• C. $\frac{9}{15}$
• D. $\frac{10}{15}$

Answer 1

The correct option is A $\frac{7}{15}$

Amount of pizza eaten by Alex= $\frac{1}{3}$

Amount of pizza given to his friend
= $\frac{1}{5}$

So, total pizza eaten by Alex and his friend
= $\frac{1}{3}$ + $\frac{1}{5}$

= $\frac{(5+3)}{\left(15\right)}$

= $\frac{8}{15}$

Therefore, Amount of pizza left with Alex
= 1 - $\frac{8}{15}$

= $\frac{15-8}{15}$

= $\frac{7}{15}$
