To simplify the fraction \( \frac{36}{48} \), we can find the greatest common divisor (GCD) of the numerator and the denominator.
The GCD of 36 and 48 is 12.
Now, we can divide both the numerator and the denominator by their GCD:
\[ \frac{36 \div 12}{48 \div 12} = \frac{3}{4} \]
Therefore, the simplified form is:
\[ \frac{36}{48} = \frac{3}{4} \]
So the answer to your expression \( \frac{36}{48} = \frac{?}{?} \) is:
\[ \frac{3}{4} \]
