Simplify $7\frac{1}{2}-\left(2\frac{1}{2}+3\right)\div16\frac{1}{2}$ and correct your answer to the nearest whole number

Correct answer is C

$7\frac{1}{2}-\left(2\frac{1}{2}+3\right)\div16\frac{1}{2}$ ; $\frac{15}{2} - \left(\frac{5}{2}+\frac{3}{1}\right)\div \frac{33}{2}$
$\frac{15}{2} - \left(\frac{5+6}{2}\right)\div \frac{33}{2}$ ; $\frac{15}{2} - \frac{11}{2} \div \frac{33}{2}$

$\frac{11}{2}$ ÷ $\frac{33}{2}$ = $\frac{11}{2}$ * $\frac{2}{33}$

= $\frac{11}{33}$ or $\frac{1}{3}$ (when simplified)

$\frac{15}{2}$ - $\frac{1}{3}$ = $\frac{43}{6}$

7.166

The nearest whole number is 7
