1 13/20
10 plus 20-2 - 11 plus 3 is equal to 20.
3/20 + 1/10 is the same as 3/20 + 2/20 which equals 5/20 which turns out to be 1/4 or 0.25 in decimal
2/5 + 3/4 - 1/2 equals 8/20 + 15/20 - 10/20 which adds up to 8/20 This equals 4/5
Suppose the answer is x.Then x + 1/2 = 7/20 so that x = 7/20 - 1/2 = 7/20 - 10/20 = -3/20

2/7 +2/3 = 6/21 + 14/21 = 20/21
10 plus 20-2 - 11 plus 3 is equal to 20.
3/20 + 1/10 is the same as 3/20 + 2/20 which equals 5/20 which turns out to be 1/4 or 0.25 in decimal
2/5 + 3/4 - 1/2 equals 8/20 + 15/20 - 10/20 which adds up to 8/20 This equals 4/5
9/10 + 2/3 = 27/30 + 20/30 = 47/30 or 1 and 17/30
7/10 + 3/5 + 2/3 = 21/30 + 18/30 + 20/30 = 59/30 = 129/30
Suppose the answer is x.Then x + 1/2 = 7/20 so that x = 7/20 - 1/2 = 7/20 - 10/20 = -3/20
15/20 or 3/4
2 + 3 + 9 + 6 = 20
1/10 + 2/3 = 3/30 + 20/30 = 23/30.
