5%2F6m + 9%2F4 = -1%2F4
:
A good common denominator is 12, multiply equation by that
12*5%2F6m + 12*9%2F4 = 12*-1%2F4
:
Cancel out the denominators and you have;
2(5m) + 3(9) = 3(-1)
:
10m + 27 = -3
:
10m = -3 - 27
:
m = -30%2F10
:
m = -3

Check solution with a calc:
5%2F6(-3) + 9%2F4 = -1%2F4
-2.5 + 2.25 = -.25
