\[ 0.15 - 0.0750 = \frac{3}{40} = 0.075 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{15}{100}\) and \(\frac{-75}{1000}\) is \(1000\). \[ \begin{aligned} 0.15 - 0.0750 &= \frac{15 \cdot 10}{100 \cdot 10} + \frac{-75 \cdot 1}{1000 \cdot 1} \\ &= \frac{150 + -75}{1000} \\ &= \frac{75}{1000} \\&= \frac{3}{40} \end{aligned} \]
