64 subtracted from 18 = 46
64 subtracted by 48 = 16
64 subtracted from 289 = -225
80
42 subtracted by 60 = -18
By 25% I'm guessing of the number 64, so it is 64-16, which is 48.

64 - 25 = 39
They could be: 64 and 36 because 64+36 = 100 and 64-36 = 28
15/64Edit: Just to show the steps used to get to the final answer... 27/64 - 3/16 = 27/64 - 12/64 = 15/64 Snakester1962 (Supervisor)
