Solving for x...
\frac{1}{2} x+ \frac{1}{4} =  \frac{15}{16} 


Times the \frac{1}{2} , both the numerator and denominator, by 8 to get the denominator to 16.
Times the \frac{1}{4} , both the numerator and denominator, by 4 to get the denominator to 16.

Then rewrite the problem, 
\frac{8}{16}x+ \frac{4}{16} =  \frac{15}{16}

now that the denominators are all the same, you can solve...
subtract the \frac{4}{16} from both sides

you should get \frac{8}{16} x =  \frac{11}{16}

Multiply both sides by 16 (it'll cancel both the 16 out making it go away)
     8x = 11

divide each side by 8 to have the x alone

     <u>8x</u> = <u>11
</u>      8      8 
<u>
</u> You should end with x = \frac{11}{8} or 1.375<u>
