-3 3/7
-10
(t-7)/w = (-3-7)/-2 = -10/-2 = +5 ( minus over minus = plus)
x/2 - 7 = -10 x/2 = -3 x = -3 x 2 x = -6
7/10 - 1/5 = 7/10 - 2/10 = 5/10 = 1/2
(7-3)/10 = 4/10 = 2/5
3/10.
4 over 10
1/10 is.
3/2 - 7/10 = 15/10 - 7/10 = 8/10 = 4/5
7/10 - 4/10 = 3/10
10 minus -7 is the same as 10+7. So, 10--7=17.
9/10 − 2/3 = 7/30
14/20 - 3/5 = 7/10 - 6/10 = 1/10
3 4/7 minus 1/7 is 3 3/7
10/15 - 3/15 = 7/15
6 and 11/14
