Question

(2,5+1 целая 2/3)*(3 целых 1/3 - 1 целая 14/15)

Answer 1

(2,5 + 1 2/3) · (3 1/3 - 1 14/15) = 5 целых 5/6.

1) 2,5 + 1 2/3 = 2 1/2 + 1 2/3 = 2 3/6 + 1 4/6 = 3 7/6 = 4 1/6

2) 3 1/3 - 1 14/15 = 3 5/15 - 1 14/15 = 2 20/15 - 1 14/15 = 1 6/15 = 1 2/5

3) 4 1/6 · 1 2/5 = 25/6 · 7/5 = (5·7)/(6·1) = 35/6 = 5 5/6
