\[ \frac{3}{4} - \frac{4}{18} = \frac{19}{36} = 0.52\overline{7} \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{3}{4}\) and \(\frac{-4}{18}\) is \(36\). \[ \begin{aligned} \frac{3}{4} - \frac{4}{18} &= \frac{3 \cdot 9}{4 \cdot 9} + \frac{-4 \cdot 2}{18 \cdot 2} \\ &= \frac{27 + -8}{36} \\ &= \frac{19}{36} \end{aligned} \]
