9/10 - 2/5= 9/10 - 4/10= 5/10= 1/2
10 minus 3 and 2/5 = 7 minus 2/5 = 63/5
It is: 8/10 minus 2/5 = 2/5
It is: 1/2 minus 2/5 = 1/10
4/5 minus 1/2 = 3/10
2/5 - 3/10 = 4/10 - 3/10 = 1/10
7/10 - 2/5 = 3/10 or three tenths
It is: 4/5 minus 3/10 = 1/2
7/10 - 2/5(4/10) = 3/10
10 and 2/5
21/25 − 2/5 = 11/25
2/5 - 1/10 = 4/10 - 1/10 = 3/10
-7/10 - 2/5 = -7/10 - (2×2)/(5×2) = -7/10 - 4/10 = -11/10 = -1 1/10
