You asked:

Evaluate the expression: \(\frac{1}{2} - \frac{3}{20}\)

MathBot Answer:

\[ \frac{1}{2} - \frac{3}{20} = \frac{7}{20} = 0.35 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{1}{2}\) and \(\frac{-3}{20}\) is \(20\). \[ \begin{aligned} \frac{1}{2} - \frac{3}{20} &= \frac{1 \cdot 10}{2 \cdot 10} + \frac{-3 \cdot 1}{20 \cdot 1} \\ &= \frac{10 + -3}{20} \\ &= \frac{7}{20} \end{aligned} \]
