Question

The numerator and denominator of a rational number are in the ratio 3: 4.8
denominator is increased by 3, the ratio becomes 3:5. Find the rational number​

Answer 1

Answer:

Step-by-step explanation:

Let the numerator be 3x

Let denominator be 4x

According to the question,

3x/ 4x+3 = 3/5

15x = 3(4x+ 3)

15x = 12x + 9

15x-12x = 9

3x = 9

 x = 9/3

x = 3

numerator = 3x= 3 x 3 = 9

denominator = 4x = 4 x 3 =12

the rational number = 9/ 12
