**Alex**, Sunday, March 23, 2008 at 6:37pmSet up an equation.

8 3/4 + x = 11 1/8

Isolate the variable...

x= 11 1/8 - 8 3/4

Find a common denominator (in this case, 8.) You can also, as I'm going to do, convert the mixed numbers into improper fractions.

x= 89/8 - 38/8

Now solve that, convert it back to a mixed number, and there you have it.
