(3 5/6-2/6)+4
2 1/7+ ( 4/7+1 2/7)
6 2/5- (1 3/5 - 1/5)
( 3 7/8+1/8)- 2 5/8
79 + ( 1 2/9 - 5/9)
( 4 2/5 + 4/5) + 1 4/5
6 1/4 - ( 3 2/4 + 1 1/4)
( 5 - 2 3/8) - 7/8

Answer 1

(3 5/6-2/6)+4= 3 3/6 + 4= 7 1/2
2 1/7+ ( 4/7+1 2/7)= 2 1/7 + 1 6/7=4
6 2/5- (1 3/5 - 1/5)= 6 2/5 - 1 2/5=5
( 3 7/8+1/8)- 2 5/8 = 4 - 2 5/8=1 3/8
79 + ( 1 2/9 - 5/9)= 7/9 + 6/9= 13/9=1 4/9
( 4 2/5 + 4/5) + 1 4/5= 5 1/5+ 1 4/5=7
6 1/4 - ( 3 2/4 + 1 1/4)= 6 1/4 - 4 3/4= 1 1/2
( 5 - 2 3/8) - 7/8= 2 58- 7/8= 1 6/8= 1 3/4
