Вычислим значение выражения по действиям:
1) 1 1/12+1 1/4 = 1+ 1+ 1/12 + 1/4 = 2 + 1/12 + 3/12 = 2 + 4/12 = 2 + 1/3 = 2 1/3
2) 2 1/3 * 1 19/56 = 7/3 * 75/56 = (7* 75) /(3 * 56) = 75/(3 * 8) = 25/8 = 3,125
3) 2 5/8*1 3/7*1 1/9 = 21/8 * 10/7 * 10/9 = (21*10*10)/(8*7*9) = (3*5*5)/(2*9) = 25/6 = 4 1/6
(1 1/12+1 1/4)*1 19/56+2 5/8*1 3/7*1 1/9 = 4 1/6
Ответ: 4 1/6
