Question

The denominator of a fraction us twice it's numerator. If 1is added to both numerator and denominator the fraction becomes 2/3.frame linear equation to the above data and find the fraction

Answer 1

Let the numerator be x

Denominator = 2x − 2

Therefore the fraction = x/2x − 2

Given when 3 is added to both the numerator and denominator, the fraction becomes 2/3.

Hence (x + 3)/(2x  − 2 + 3) = 2/3

⇒ (x + 3)/(2x + 1) = 2/3

⇒ 3x + 9 = 4x + 2

⇒ x = 7

Therefore the fraction is 7/12.

thanks

Answer 2

So the fraction will be 1/2
