Correct Answer: Option D
Explanation
(7frac{1}{2}-left(2frac{1}{2}+3right)div16frac{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
