Question

the denominator of a rational number is 2 more than its numerator. if 3 is added to the denominator, the number obtained is 1/2.find the original rational number.​

Answer 1

Answer:

Rational number is 5/7

Step-by-step explanation:

let the numerator be x

then the rational number is x/(x+2)

given x/(x+2+3) = 1/2

=> x/(x+5) = 1/2

=> 2x = x + 5

=> 2x - x = 5

=> x = 5

therefore the number is x/x+2 = 5/(5+2) => 5/7
