Question

Numerator Denominator of a ratinol no. are in ratio of 3:4.if denominator is increased by 3 the ratio will be 3:5. Find the ratinol no.

Answer 1

Answer:

9/12

Step-by-step explanation:

Let the numerator be 3a and denominator be 4a.

If denominator is increased by 3:

= > 3a : (4a + 3) = 3 : 5

= > 5 * 3a = 3(4a + 3)

= > 15a = 12a + 9

= > 15a - 12a = 9

= > 3a = 9

= > a = 3

Hence that rational number is 3a/4a = 3(3)/4(3)

That rational number is 9/12
