Ответ:

  1. \(7\frac{5}{24}-x=2\frac{5}{16}\).

    \(x=7\frac{5}{24}-2\frac{5}{16}=7\frac{10}{48}-2\frac{15}{48}=5-\frac{5}{48}=4\frac{43}{48}\).

    Ответ: \(x=4\frac{43}{48}\).

  2. \(\left(x+\frac{5}{12}\right)-\frac{9}{20}=\frac{11}{15}\).

    \(x=\frac{11}{15}+\frac{9}{20}-\frac{5}{12}=\frac{44}{60}+\frac{27}{60}-\frac{25}{60}=\frac{46}{60}=\frac{23}{30}\).

    Ответ: \(x=\frac{23}{30}\).
