i rlly need help

Hey there! I can help you with part of your homework! :)
14. Solve.
([tex]\frac{5}{13} +\frac{3}{91}[/tex]): ([tex]\frac{20}{13} -\frac{3}{39}[/tex])
First, let's concentrate on [tex]\frac{5}{13} +\frac{3}{91}[/tex]
We must find the common denominator.
The common denominator is 91! :)
[tex]\frac{}{91} +\frac{}{91}[/tex]
Yeah! Now for the numerators:
[tex]\frac{35}{91}[/tex][tex]+[/tex][tex]\frac{3}{91}[/tex]
Now we can add those two fractions:
[tex]\frac{38}{91}[/tex]
Hope it helps!
