You asked:

Evaluate the expression: \(\frac{3}{4} - \frac{2}{5}\)

MathBot Answer:

\[ \frac{3}{4} - \frac{2}{5} = \frac{7}{20} = 0.35 \]


The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{3}{4}\) and \(\frac{-2}{5}\) is \(20\). \[ \begin{aligned} \frac{3}{4} - \frac{2}{5} &= \frac{3 \cdot 5}{4 \cdot 5} + \frac{-2 \cdot 4}{5 \cdot 4} \\ &= \frac{15 + -8}{20} \\ &= \frac{7}{20} \end{aligned} \]
