\(\frac{9}{8}\) + \(\frac{5}{{16}}\) = \(\frac{{18}}{{16}}\) + \(\frac{5}{{16}}\) = \(\frac{{23}}{{16}}\)

\(\frac{9}{7}\) – \(\frac{6}{5}\) = \(\frac{{45}}{{35}}\) – \(\frac{{42}}{{35}}\) = \(\frac{3}{{35}}\)

\(\frac{7}{{32}}\) × \(\frac{{96}}{7}\) = 3

\(\frac{9}{8}\) : \(\frac{4}{6}\) = \(\frac{9}{8}\) × \(\frac{6}{4}\) = \(\frac{{27}}{{16}}\)
