Question

2 1/10+(-4 4/5)+(1 11/15)+(-1 1/6)= ​

Answer 1

Ответ:

-2 2/15

Пошаговое объяснение:

1) 2 1/10 + (-4 4/5) = 2 1/10 - 4 4/5 = 2 1/10 - 4 8/10 = -2 7/10

2) -2 7/10 + 1 11/15 = -2 21/30 + 1 22/30 = -1 51/30 + 1 22/30 = -29/30

3) -29/30 + (-1 1/6) = -29/30 - 1 1/6 = -29/30 - 1 5/30 = -1 34/30 = -2 4/30 = -2 2/15
