216 as a rational number with numerator 5​

Answer 1

Answer:

Step-by-step explanation:

90 ÷ 18 = 5

216 ÷ 18 = 12

Hence, 90/216 as a rational number with numerator 5 is 5/12.

Answer 2

Given: A fraction  $\frac{90}{216}$

To find: An equivalent fraction of the given fraction having 5 as numerator

Solution:

To get the equivalent fraction having 5 as the numerator, we need to find a number by which both numerator and denominator can be divided such that the numerator becomes 5.

To find such a number, we need to divide 90 by 5.

We get,

∵ 90 ÷ 5 = 18

So, 18 is the required number.

∴ $\frac{90}{216} = \frac{90}{216}$ ÷ $\frac{18}{18} = \frac{5}{12}$

Hence,  $\frac{90}{216}$ can be expressed as $\frac{5}{12}$, which has 5 as numerator.
