8/5 - 4/9
= 72/45 - 20/45
= 52/45
= 1 7/45
4/5 - 1/8 = 32/40 - 5/40 = 27/40
3/10 - 4/5 = 3/10 - 8/10 = -5/10 = -1/2
Subtract 7/24 from 4/8 to get 5/244/8 * 3/3 = 12/2412/24 -5/24 = 7/24

6 over 8 3 over 4
= 2/5-8/2 = (2/5)-(8/2) = (4/10)-(40/10) = -36/10 = -18/5 Or as a decimal, -3.6
3/4 minus 7/8 = -1/8
9 and 6/8
8 and 5 over 6
If you mean (2/5 times 30) minus (4/3 times 15/8) then the answer is 19/2 or 9.5
8 and 5/15 - 3 and 8/15 = 4 and 12/15 = 4 and 4/5
1 and a half
