Question

Find the equivalent fraction of 3/5 having (a) denominator 20 (b) numerator 9?

Answer 1

3/5

(a) Denominator 20

3/5*4/4 = 12/20

(b) Numerator 9

3/5*3/3 = 9/15

Hope it helps :)

Answer 2

Here is the answer

(a) Denominator 20

In order to get denominator 20,

We will have to multiply the numerator and denominator of the given fraction by 4

{ 5 × 4 = 20 }

$\bf{\therefore \frac{3}{5} = \frac{3}{5} \times \frac{4}{4} }$

$\bf{= \frac{12}{20} }$
Hence,
We got 20 as the denominator.

Similarly
In (b),

Multiply the numerator and denominator by 3 in order to get 3 as the numerator 9

{ 3×3 = 9 }

$\bf{\therefore \frac{3}{5} = \frac{3}{5} \times \frac{3}{3} }$

$\bf {= \frac{9}{15}}$

Hence,
We got numerator as 9.
