16 − 10/11 = 151/11
10/4 - z - 8/16 = 21/2 - z - 1/2 = 2 - z
16/25 - 10/25 = 6/25
1/2 − 3/16 = 10/32 which simplifies to 5/16
Find the least common denominator of 10 and 15, which is 30. If 15 is doubled to 30, the 8 over it must be doubled to 16. If 10 is tripled to 30, the 9 over it must be tripled to 27. 27 over 30 minus 16 over 30 is 11 over 30.

11/12 minus 1/16 is 41/48
19/24 minus 7/16 is 17/48
26 - 10 = 16
21/30 - 5/30 = 16/30 = 8/15
