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.
15.
16 minus -11 is 27.
10/4 - z - 8/16 = 21/2 - z - 1/2 = 2 - z
16 10/11 - 9 = 7 10/11
16/25 - 10/25 = 6/25
1 minus 5/16 = 11/16.
