(a) numerator 9.
We will reduce the fraction \(\frac{36}{48}\) by dividing both the numerator and the denominator by \(4\) to get the numerator \(9\).
\(\frac{36 }{ 48} ÷ \frac{4 }{ 4} \)
\(= \frac{9 }{ 12}\)
(b) denominator 4.
We will reduce the fraction\(\frac{36}{48}\) by dividing both the numerator and the denominator by \(12\) to get the denominator \(4\).
\(\frac{36 }{ 48} ÷ \frac{12}{ 12}\)
= \(\frac{3 }{ 4}\)
