Question

the denominator of the one upon under 12

Answer 1

1/12 = the denominator is 12 itself.

Answer 2

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.
