1) Вычислите: а) \(\frac{15}{29}-\frac{9}{29}\cdot\frac{2}{9}+\frac{5}{12}\); б) \(6,3-0,07\); в) \(8\frac{3}{19}-7\frac{15}{19}\).

1. \(\frac{15}{29}-\frac{9}{29}\cdot\frac{2}{9}+\frac{5}{12}=\frac{15}{29}-\frac{2}{29}+\frac{5}{12}=\frac{13}{29}+\frac{5}{12}=\frac{156+145}{348}=\frac{301}{348}\).
2. \(6,3-0,07=6,23\).
3. \(8\frac{3}{19}-7\frac{15}{19}=\frac{155}{19}-\frac{148}{19}=\frac{7}{19}\).

Ответ: а) \(\frac{301}{348}\); б) 6,23; в) \(\frac{7}{19}\).
