Question

Numerator and denominator of a fraction are in the ratio of 3:5 . if 4 is subtracted from the numerator,it reduces to 2/5.find the fraction.​

Answer 1

Answer:

3/5

Step-by-step explanation:

if numerator and denominator of a fraction is in a ratio, the ratio in simplest form is equal to the fraction in simplest form

i.e. if numerator and denominator are in ratio 3:5

=> the fraction is 3/5

...

still let's do it in the formal way

given, numerator and denominator of a fraction are in the ratio of 3:5

so let numerator be 3x and denominator be 5x

also given, if 4 is subtracted from the numerator, it reduces to 2/5

=> (3x-5)/5x = 2/5

=> 15x-25 = 10x

=> 5x = 25

=> x = 5

=> 3x/5x = 15/25 = 3/5
