Step 1
A proportion is an equality of 2 fractions, so to check if 2 fractions form a proportion you have to check if they are equal.
$L=\frac{9}{24}=\frac{3}{8}$
$R=\frac{15}{40}=\frac{3}{8}$
Both sides are equal, so the fractions form a proportion.
$\frac{9}{24}=\frac{15}{40}$

Step 1
This proportion is equal to 2 fractions, so to check if 2 fractions of a proportion are equal, you must check if they are equal.
$L=\frac{9}{24}$
Lets reduce the fraction to simplest form by calculating HCF of numerator and denominator, which is 3 and then dividing both by 3
$\therefore \frac{9}{24}=\frac{9÷3}{24÷3}$
$\therefore \frac{9}{24}=\frac{3}{8}$
$R=\frac{15}{40}$
Lets reduce the fraction to simplest form by calculating HCF of numerator and denominator, which is 5 and then dividing both by 5
$\therefore \frac{15}{40}=\frac{15÷5}{40÷5}$
$\therefore \frac{15}{40}=\frac{3}{8}$
Both sides are equal, so the fractions form a proportion.
$\frac{9}{24}=\frac{15}{40}$
