Answer 1

1) 7/8 - 3/5 = 11/40
2) 2/3 + 1/2= 7/6
3) 60:4 5/7 = 6:33/7=6*7/33= 140/11
4) 11/40:7/6=11/40*6/7= 33/140
5) 33/140*140/11= 3 
ответ: 3

Answer 2

Calculation:

To solve the expression (7/8 - 3/5) : (2/3 + 1/2) * (60 : (4 + 5/7)), we need to follow the order of operations (PEMDAS/BODMAS).

1. Simplify the expression inside the parentheses: - (4 + 5/7) = 4 35/7 = 4 5/7 - (60 : (4 + 5/7)) = 60 : (4 5/7) = 60 : 4 5/7

2. Perform the division operation: - (7/8 - 3/5) = (35/40 - 24/40) = 11/40 - (2/3 + 1/2) = (4/6 + 3/6) = 7/6 - (60 : 4 5/7) = (60 : 32/7) = 60 * 7/32 = 420/32 = 15/8

3. Perform the multiplication operation: - (11/40) : (7/6) * (15/8) = (11/40) * (6/7) * (15/8) = 99/128

Therefore, the result of the expression (7/8 - 3/5) : (2/3 + 1/2) * (60 : (4 + 5/7)) is 99/128.
