Question

Out of a pizza, Prof. Burgers ate $\frac{2}{11}$, while Nexus ate $\frac{3}{11}$. How much of the pizza is left?

• A. $\frac{6}{11}$
• B. $\frac{5}{11}$
• C. $\frac{7}{11}$
• D. $\frac{4}{11}$

Answer 1

The correct option is A $\frac{6}{11}$

Prof. Burgers ate $\frac{2}{11}$, so the pizza left is:
$1-\frac{2}{11}=\frac{11}{11}-\frac{2}{11}=\frac{9}{11}$
From this, Nexus ate:
$\frac{3}{11}$.
So, the remaining pizza is:
$\frac{9}{11}-\frac{3}{11}=\frac{9-3}{11}=\frac{6}{11}$
