Question

Выполнить действия (6 5/8-1/2)-(5 3/4-2 1/6)+(9 5/8-7 1/3)

Answer 1

( 6 5/8 - 1/2 ) - (5 3/4 - 2 1/6) + (9 5/8 - 7 1/3)= 4 5/6
1) 6 5/8 - 1/2 = 6 5/8 - 4/8= 6 1/8
2) 5 3/4 -  2 1/6 = 5 9/12 - 2 2/12 = 3 7/12 
3) 9 5/8 - 7 1/3 = 9  15/24 - 7 8/24 = 2  7/24 
4) 6 1/8 - 3 7/12 =  6  3/24 - 3 14/24 = 2 13/24
5) 2 13/24 + 2 7/24 = 4  20/24 = 4 5/6

Answer 2

(6 5/8-4/8)-(5 9/12-2 2/12)+(9 15/24-7 8/24)=6 1/8-3 7/12 +2 7/24=
6 3/24-3 14/24+2 7/24=5 27/24-3 14/24+2 7/24=4 20/24=4 5/6
