3/5 minus 3/10 is the same as 6/10 minus 3/10 = 3/10
3/5=12/20 1/4=5/20 3/5-1/4=7/20
5/6 - 3/4 = 10/12 - 9/12 = One-twelfth.
3/5 is 6/10. (6-3)/10 is 3/10
9/10 - 3/5 = 9/10 - 6/10 = 3/10 or 3 over 10
3/5 − 9/10 = -3/10
3/10 - 4/5 = 3/10 - 8/10 = -5/10 = -1/2
1/5 + 3/10 = 2/10 + 3/10 = 5/10 = 1/2
4/5 - 3/10 = 8/10 - 3/10 = 5/10 = 1/2
4/10 - 3/5 = 2/5 - 3/5 = -1/5
(1/5) / (3/10) = (1/5) x (10/3) = 10/15 = 2/3
2/5 - 3/10 = (2×2)/(5×2) - 3/10 = 4/10 - 3/10 = (4-3)/10 = 1/10.
No ------------------------------------------------ 4/5 = (4×2)/(5×2) = 8/10 8 ≠ 3 → 8/10 ≠ 3/10 → 4/5 ≠ 3/10
