\[ \frac{13}{25} + \frac{18}{5} - \frac{5}{10} = \frac{181}{50} = 3.62 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{13}{25}\), \(\frac{18}{5}\), and \(\frac{-5}{10}\) is \(50\). \[ \begin{aligned} \frac{13}{25} + \frac{18}{5} - \frac{5}{10} &= \frac{13 \cdot 2}{25 \cdot 2} + \frac{18 \cdot 10}{5 \cdot 10} + \frac{-5 \cdot 5}{10 \cdot 5} \\ &= \frac{26 + 180 + -25}{50} \\ &= \frac{181}{50} \end{aligned} \]
