6-(5+2/5)

Answer 1

1/2 + 1/10 = (10+2)/10 = 12/20 = 3/4

4 + 3/8 - (3 + 1/2) = 4 + 3/8 - (6+1)/2 = (32 + 24 - 28)/8 = 28/8 = 7/2

6 + 2/3 +1/3 = (18+2+1)/3 = 21/3 = 7

1 -2/3 = (3-2)/3 = 1/3

7 +15/18 - 2/3 = (18*7 + 15 + 6*2)/18 = 129/18 = 43/6

4 + 1/5 + 2/7 = (35*4 +7 + 5*2)/35 = 157/35

9/11 + 10 = (9 + 11*10)/11 = 119/11

23/6 + 20/6 = (23+20)/6 = 43/6

6 - (5 +2/5) = 6 - (5*5 + 2)/5 = 6 - 27/5 = (5*6 -27)/5 = 3/5
