Question

-6.6+4/5+(-1.2/3)+3.4

Answer 1

- 6,6 = - 6 6/10 = - 6 3/5
3,4 = 3 4/10 = 3 2/5
А теперь решаем:
1) - 6 3/5 + 4/5 = - 5 8/5 + 4/5 = - 5 4/5
2) - 5 4/5 - 1 2/3 = - 29/5 - 5/3 = - 87/15 - 25/15 = - 112/15 = - 7 7/15
3) - 7 7/15 + 3 2/5 = - 112/15 + 17/5 = - 112/15 + 51/15 = - 61/15 = - 4 1/15
