1.108 Решите уравнение: а) x + 5/18 = 11/36; б) 7/12 − x = 5/6; в) 9/16 · x = 3/8; г) x : 7/34 = 1/8.

1. \(x+\frac{5}{18}=\frac{11}{36}\)

   \(x=\frac{11}{36}-\frac{10}{36}=\frac{1}{36}\)

2. \(\frac{7}{12}-x=\frac{5}{6}\)

   \(-x=\frac{5}{6}-\frac{7}{12}=\frac{10}{12}-\frac{7}{12}=\frac{1}{4}\)

   \(x=-\frac{1}{4}\)

3. \(\frac{9}{16}x=\frac{3}{8}\)

   \(x=\frac{3}{8}:\frac{9}{16}=\frac{3}{8}\cdot\frac{16}{9}=\frac{2}{3}\)

4. \(x:\frac{7}{34}=\frac{1}{8}\)

   \(x=\frac{1}{8}\cdot\frac{7}{34}=\frac{7}{272}\)

Ответ: а) \(x=\frac{1}{36}\); б) \(x=-\frac{1}{4}\); в) \(x=\frac{2}{3}\); г) \(x=\frac{7}{272}\).
