Question

Вычислите:
1) (2/3 + 5/8 - 11/12) *5 1/3=...
2) 15 4/7- 4 3/8 * (1 3/7 - 34/35)=...

Comments

(2/3+5/8-11/12)* 5целых 1/3= и 2) 15целых 4/7- 4целых 3/8* (1целая 3/7- 34/35) =

Answer 1

(2/3 + 5/8 - 11/12) *5 1/3=(16/24+15/24-22/24)*16/3=9/24*16/3=2

15 4/7- 4 3/8 * (1 3/7 - 34/35)=13 4/7
1) 1 3/7-34/35=10/7-34/35=50/35-34/35=16/35
2) 4 3/8*16/35=35/8*16/35=2
3) 15 4/7-2=13 4/7
