Short Answer

Expert verified

On simplifying the given expression, we get

$\frac{2}{5} + \frac{5}{8} - \frac{3}{4} = \frac{11}{40}$

Step by step solution

Step 1. Given information

$\begin{array}{l} Thegivenexpressionis \\ \frac{2}{5} + \frac{5}{8} - \frac{3}{4} \\ Wehavetosimplifythegivenexpression. \end{array}$

Step 2. Take the LCM of denominator

$\begin{array}{l} \Rightarrow \frac{2}{5} + \frac{5}{8} - \frac{3}{4} = \frac{2 \times 8 + 5 \times 5 - 3 \times 10}{40} \\ \Rightarrow \frac{2}{5} + \frac{5}{8} - \frac{3}{4} = \frac{16 + 25 - 30}{40} \end{array}$

Step 3. Simplify the fractions

$\begin{array}{l} \Rightarrow \frac{2}{5} + \frac{5}{8} - \frac{3}{4} = \frac{16 + 25 - 30}{40} \\ \Rightarrow \frac{2}{5} + \frac{5}{8} - \frac{3}{4} = \frac{11}{40} \end{array}$
