Answer
$\frac{28}{36}$
Work Step by Step
$ \frac{7}{9}= \frac{}{36}$
Convert the denominator of the first fraction to match the indicated denominator. The 9 must be converted to a 36.
$ 36\div9= 4$
The numerator and denominator of the first fraction must therefore be multiplied by 4. So,
$\frac{7\times4}{9\times4}= \frac{28}{36}$
