Question

(5 целых 3/8+18 целых 1/2-7целых5/24)÷16целых2/3

помогите

Answer 1

1)5 3/8  +  18 1/2 = 43/8  +  37/2 =(43 × 1  +  37 × 4)/8 = 43/8  +  148/8 =  191/8 = 23 7/8
2) 23 7/8 - 7 5/24 = 191/8  - 173/24 = (191 × 3 - 173 × 1)/24 = 573/24  -  173/24 =  400/24 = 50/3 = 16 2/3
3) 16 2/3 ÷ 16 2/3 =50/3  ÷  50/3 = 50/3  ×  3/50 =  1
ответ 1

Answer 2

(5 3/8 + 18 1/2 - 7 5/24) : 16 2/3 = 1,

1) 5 3/8 + 18 1/2 - 7 5/24 = (5 + 18 - 7) + (3/8 + 1/2 - 5/24) =
    = 16 + (9/24 + 12/24 - 5/24) = 16 + 16/24 = 16 + 2/3 = 16 2/3,
2) 16 2/3 : 16 2/3 = 1
