Question

If 5 of your friends eat one slice each from a medium-sized pizza containing 6 equal slices, what fraction of the pizza is left?

• A. $\frac{5}{6}$
• B. $\frac{3}{6}$
• C. $\frac{1}{6}$
• D. $\frac{4}{6}$

Answer 1

The correct option is C

$\frac{1}{6}$

Total number of slices = 6
Number of slices that my friends eat = 5
So, the fraction of pizza that my friends eat = $\frac{5}{6}$
We know that,
Fraction of pizza that my friends eat + Fraction of pizza left = 1
$\therefore$ Fraction of pizza left
= 1 - Fraction of pizza that my friends eat
$=1-\frac{5}{6}$
$=\frac{6}{6}-\frac{5}{6}$
$=\frac{6-5}{6}$
$=\frac{1}{6}$
