3/10 - 4/5 = 3/10 - 8/10 = -5/10 = -1/2
9/10 − 2/5 = 1/2
The difference is 1/10 -------------------------------------------- 7/10 - 3/5 Well 3/5 is the same as 6/10 (doubling both top and bottom). So the comparison can now be written as 7/10 - 6/10 And as you can see the difference is one tenth 1/10

9 and 6/8
3/10 - 4/5 = 3/10 - 8/10 = -5/10 = -1/2
9/10 - 6/10 = 3/10
3/2 − 6/5 = 3/10
17 1/10
25/40 - 12/40 = 13/40
9/10 − 2/5 = 1/2
2 over 9
The difference is 1/10 -------------------------------------------- 7/10 - 3/5 Well 3/5 is the same as 6/10 (doubling both top and bottom). So the comparison can now be written as 7/10 - 6/10 And as you can see the difference is one tenth 1/10
The question is: 2/3 - 1/5 LCM is 15. So, 2/3 becomes 10/15 and 1/5 becomes 3/15. 10/15 - 3/15 is (10-3)/15 [The whole term over 15] So, we get 7/15. The answer is 7/15.

7/3 − 2/3 = 5/3 or 12/3
