how to make a fraction in it's lowest term?

Answer :

we follow these steps to get fraction in it's lowest term :

Step 1 :  Break down both the numerator (top number) and denominator (bottom number) into their prime factors.

For example, suppose you want to reduce the fraction $\frac{72}{99}$. Break down both 72 and 99 into their prime factors:

$\frac{72}{99}$ = $\frac{2 \times 2 \times 2 \times 3 \times 3}{3 \times 3 \times 11}$


Step 2 : Cross out any common factors.

In this example, you cross out both  3 , because they’re common factors — that is, they appear in both the numerator and denominator:

$\frac{72}{99}$ = $\frac{2 \times 2 \times 2 \times \cancel{3} \times \cancel{3}}{\cancel{3} \times \cancel{3} \times 11}$


Step 3 : Multiply the remaining numbers to get the reduced numerator and denominator.

This shows you that the fraction $\frac{72}{99}$ reduces to $\frac{8}{11}$:

$\frac{72}{99}$ = $\frac{2 \times 2 \times 2 \times \cancel{3} \times \cancel{3}}{\cancel{3} \times \cancel{3} \times 11}$  = $\frac{8}{11}$
