16
The answer is 6/7 minus 2/5 = 16/35
-2 no way the question is 7--9 which is 16
38 minus 16 is 22.
1/4 = 4/16 - multiply top and bottom by 4. Now both numbers are 16ths so just subtract 4 from 7 and the answer is 3, (3/16) I think your calculation must be 7/16 minus 1/4 because you can't subtract 7 from 4.
-16 minus -9 is -7
19/24 minus 7/16 is 17/48
23 - 7 = 16
7/16 - 4/16 = 3/16
7
16 minus 9 = 7
25 + 16 - 13 - 21 = 7
16
16/7 - 1 = 1.285714 recurring (that is, 1.285714285714...)
14/16 - 9/16 = 5/16
The answer is 6/7 minus 2/5 = 16/35
16:45 - 7:00 = 9:45.
