3/4 − 3/10 = 9/20
10/12 minus 2/4 is 1/3
3/10.
4 over 10
3/4 − 3/10 = 18/40 or 9/20
It is: 4/5 minus 1/2 = 3/10
(7-3)/10 = 4/10 = 2/5
4/5 - 3/10 = 8/10 - 3/10 = 5/10 = 1/2
2/5 = 4/10 minus 1/10 is 3/10
7/10 - 4/10 = 3/10
2/5 - 3/10 = (2×2)/(5×2) - 3/10 = 4/10 - 3/10 = (4-3)/10 = 1/10.
4/5 - 2/10 = 4/5 - 1/5 = 3/5
3/2 - 7/10 = 15/10 - 7/10 = 8/10 = 4/5
