1 7/9
Пошаговое объяснение:
3 1/3 + 2,5 = 10/3 + 25/10 = 10/3 + 5/2 = 20/6 + 15/6 = 35/6
4,6 - 2 1/3 = 46/10 - 7/3 = 23/5 - 7/3 = 69/15 - 35/15 = 34/15
35/6*34/15 = 7/6*34/3 = 238/18 = 13 4/18 = 13 2/9
4,5 *1 2/3 = 45/10 * 5/3 = 45/2*1/3 = 15/2*1/1 = 15/2 = 7,5
7,5 - 6/75 = 0,75
(1 1/3)^3 = (4/3)^3 = 64/27
75/100*64/27 = 25/100*64/9 = 25/25*16/9 = 16/9 = 1 7/9
