Вычислите: 8/9*3/4-(5/6-1/4)

1) 5/6 - 1/4 = 10/12 - 3/12 = 7/12 2) 8/9 • 3/4 = 2/3 3) 2/3 - 7/12 = 8/12 - 7/12 = 1/12 Ответ 1/12

[latex] frac{8}{9} *frac{3}{4}-( frac{5}{6}-frac{1}{4})= frac{8*3}{9*4}- frac{10-3}{12} = frac{24}{36} - frac{7}{12} = frac{24-21}{36} = frac{3}{36}= frac{1}{12} [/latex]
