You asked:

Evaluate the expression: \(\frac{10}{4} - \frac{9}{5}\)

MathBot Answer:

\[ \frac{10}{4} - \frac{9}{5} = \frac{7}{10} = 0.7 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{10}{4}\) and \(\frac{-9}{5}\) is \(20\). \[ \begin{aligned} \frac{10}{4} - \frac{9}{5} &= \frac{10 \cdot 5}{4 \cdot 5} + \frac{-9 \cdot 4}{5 \cdot 4} \\ &= \frac{50 + -36}{20} \\ &= \frac{14}{20} \\&= \frac{7}{10} \end{aligned} \]
