№ 26. Числитель: (17 1/3 : 19 1/2 + 1 1/12) * 3 + 3 7/12 = 9 1/2
1) 17 1/3 : 19 1/2 = 52/3 * 2/39 = 104/117 = 8/9
2) 8/9 + 1 1/12 = 32/36 + 1 3/36 = 1 35/36
3) 1 35/36 * 3 = 71/36 * 3 = 71/12 = 5 11/12
4) 5 11/12 + 3 7/12 = 8 18/12 = 9 6/12 = 9 1/2
Знаменатель: 1 23/50 - 3 6/100 : (55 65/100 : 5 3/10 - 4 1/2) = 95/100
1) 55 65/100 : 5 3/10 = 5565/100 * 10/53 = 5565/530 = 10 265/530 = 10 1/2
2) 10 1/2 - 4 1/2 = 6
3) 3 6/100 : 6 = 306/100 * 1/6 = 306/600 = 51/100
4) 1 23/50 = 51/100 = 1 46/100 - 51/100 = 95/100
Числитель/знаменатель: 9 1/2 : 95/100 = 19/2 * 100/95 = 50/5 = 10
