Question

The sum of the numerator and denominator of a
fraction is 3 less than twice the denominator. If the
numerator and denominator are decreased by 1,
the numerator becomes half the denominator.
Determine the fraction.​

Answer 1

by solving the fraction is 4/7.

Answer 2

Answer:

Step-by-step explanation:

Equation 1 => N + D = 2D +3

Equation 2 => (N-1)/(D-1) = 1/2

$N-1\frac{x}{y} D-1 = 1\frac{x}{y} 2$

From (1) and (2), we get

N - D = -3 .............. (3)

2N - 2 = D - 1  (or) 2N - D = +1  ....... (4)

Solving further,

(3) - (4) gives,

N = 4  ......... (5)

From (3) and (5), we get

D = 7.
