Adding \(4\frac{1}{2}\) to \(3\frac{3}{4}\) and then subtracting \(2\frac{2}{5}\)from the sum results in which value?

Explanation

Your first step is to convert mixed numbers to fractions: 9/2 + 15/4 -12/5
The lowest common denominator is 20. Convert each fraction, then combine: 9/2 + 15/4 -12/5=90 +75-48/20=117/20
