First, you have to find the LCD. The LCD of 4 and 7 is 28, so you rewrite the fraction:
7/28
4/28

Then you add them.
TheBlueFox

First, we need to find the lowest common denominator in order to add these fractions together. The lowest common denominator is 28 so now we are going to rewrite the equation with the equivalent fractions.

[tex]\frac{7}{28}[/tex] + [tex]\frac{4}{28}[/tex] = [tex]\frac{11}{28}[/tex]

good job
