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
A
33
B
8
C
7
D
0
correct option: d
\(7\frac{1}{2}-\left(2\frac{1}{2}+3\right)\div16\frac{1}{2}; \frac{15}{2} - \left(\frac{5}{2}+\frac{3}{1}\right)\div \frac{33}{2}\
\frac{15}{2} - \left(\frac{5+6}{2}\right)\div \frac{33}{2}; \frac{15}{2} - \frac{11}{2} \div \frac{33}{2}\
\frac{15-11}{2}\div \frac{33}{2}; \frac{4}{2} \times \frac{2}{33} = \frac{4}{33} = 0.1212\)
The nearest whole number is 0
