3/10 - 4/5 = 3/10 - 8/10 = -5/10 = -1/2
= 2/5-8/2 = (2/5)-(8/2) = (4/10)-(40/10) = -36/10 = -18/5 Or as a decimal, -3.6
1/4 - 7/10 = (5/5)(1/4) - (2/2)(7/10) = 5/20 - 14/20 = -9/20
2/5 -15 = -14.6
1/10 - 5/10 = -4/10 = -2/5
3/2 − 6/5 = 3/10
3/10 - 4/5 = 3/10 - 8/10 = -5/10 = -1/2
= 2/5-8/2 = (2/5)-(8/2) = (4/10)-(40/10) = -36/10 = -18/5 Or as a decimal, -3.6
