К) 9 \(\frac{11}{16}\) - \(\frac{7}{24}\)

К) 9 \(\frac{11}{16}\) - \(\frac{7}{24}\) = \(\frac{9 \cdot 16 + 11}{16}\) - \(\frac{7}{24}\) = \(\frac{144 + 11}{16}\) - \(\frac{7}{24}\) = \(\frac{155}{16}\) - \(\frac{7}{24}\) = \(\frac{155 \cdot 3}{16 \cdot 3}\) - \(\frac{7 \cdot 2}{24 \cdot 2}\) = \(\frac{465}{48}\) - \(\frac{14}{48}\) = \(\frac{465 - 14}{48}\) = \(\frac{451}{48}\) = 9 \(\frac{19}{48}\)

Ответ: 9 \(\frac{19}{48}\)
