Question

Помогите пожалуйста:
(3 1/2-2 2/3+5 5/6+ 4 3/5)*24=

Answer 1

(3 1/2 - 2 2/3 + 5 5/6 + 4 3/5) · 24 = 270 целых 2/5

1) 3 1/2 - 2 2/3 = 3 3/6 - 2 4/6 = 2 9/6 - 2 4/6 = 5/6

2) 5/6 + 5 5/6 = 5 10/6 = 6 4/6 = 6 2/3

3) 6 2/3 + 4 3/5 = 6 10/15 + 4 9/15 = 10 19/15 = 11 4/15

4) 11 4/15 · 24 = 169/15 · 24/1 = (169·8)/(5·1) = 1352/5 = 270 2/5
