3 - 2/10 = 2 and 8/10
2/5 - 3/10 = (2×2)/(5×2) - 3/10 = 4/10 - 3/10 = (4-3)/10 = 1/10.
3/5 + 2/10 = 6/10 + 2/10 = 8/10 = 4/5.
10/15 2/3 = 10/15 10/15 = 3/5
3/10 ÷ 1/2 = 6/10 which can be reduced to 3/5.
1/2 = 5/10 so then 5/10 - 3/10 = 2/10 = 1/5
2 3/10
1/5 x 2/2 = 2/10 2/10 + 3/10 = 5/10 = 1/2
9/10 + 3/5 = 9/10 + 6/10 = 15/10 = 3/2 or 11/2
2 over 10
3/10
3/2 - 7/10 = 15/10 - 7/10 = 8/10 = 4/5
(3/10)/(4-1/2) = (3/10)/(9/2) = (3/10) x (2/9) = 6/90 = 1/15
