3/10 - 4/5 = 3/10 - 8/10 = -5/10 = -1/2
9/10 − 2/5 = 1/2
5/12
9 and 6/8
= 2/5-8/2 = (2/5)-(8/2) = (4/10)-(40/10) = -36/10 = -18/5 Or as a decimal, -3.6
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 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.
5/12
7/3 − 2/3 = 5/3 or 12/3
9 and 6/8
= 2/5-8/2 = (2/5)-(8/2) = (4/10)-(40/10) = -36/10 = -18/5 Or as a decimal, -3.6
