Expressed as a mixed number in its simplest form, 12 5/18 - 3/4 = 11 19/36 or eleven and nineteen thirty-sixths. Expressed as a decimal, this is equal to 11.527 recurring (that is, 11.527777...)
It is -25/36
Well, darling, 17 over 18 minus 2 over 3 is the same as 17 times 3 minus 2 times 18, all over 18 times 3. So, that gives you 51 minus 36 over 54, which simplifies to 15 over 54, or 5 over 18. Math doesn't have to be a drag, honey!
3 minus 3/18 is 2 5/6
2/3 minus 12/15 is -2/15
7/12 minus 1/3 = 1/4
11/12 minus 7/12 is 1/3
3/18
-6 x -3 = 18 + (-6) = 12
12 - 18(1/3) = 12 - 55/3 = 36/3 - 55/3 = -19/3
