Simplify \(7\frac{1}{12}-4\frac{3}{4}+2\frac{1}{2}\)
- 4
- 41/6
-
45/6
- 51/6
The correct answer is: C
Explanation
\(7\frac{1}{12}-4\frac{3}{4}+2\frac{1}{2}=5\left(\frac{1-9+6}{12}\right)\\
5\left(\frac{-2}{12}\right)\\
=4\left(\frac{12-2}{12}\right)\)
(carry one from 5 and call it 12)
\(4\frac{10}{12}\\
=4\frac{5}{6}\)
