x/3 - 7 = 2=> x/3 = 9 (add 7 to both sides) => x = 27 (multiply both sides by 3).
1 3/7 (Mixed number: one and three over seven).
It is: 3 and 7/10
7 times minus 2 =
It is: 10 and 6/7 = 76/7
3/10.
(7-3)/10 = 4/10 = 2/5
1/10 is.
7/10 - 4/10 = 3/10
3/2 - 7/10 = 15/10 - 7/10 = 8/10 = 4/5
10 minus -7 is the same as 10+7. So, 10--7=17.
9/10 − 2/3 = 7/30
3 4/7 minus 1/7 is 3 3/7
9/10 minus 7/8 is 1/40
6 and 11/14
10/15 - 3/15 = 7/15
14/20 - 3/5 = 7/10 - 6/10 = 1/10
