15/20 - 6/20 = 9/20
-15
11/15 − 3/10 = 13/30
It is -25 because -15--25 = 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.
3/10 - 11/15= 9/30 - 22/30 = -13/30
2/5 -15 = -14.6
-5
-5
9/20
(1/3) + (4/10) = (5/15) + (6/15) = 11/15
10/13 × 26/15 = 4/3 or 11/3
