Question

If the numerator of a fraction is 3 less than the denominator, the fraction will be :

Answer 1

Answer:

denominator be x

numerator be 3x-x

Answer 2

Answer:

your Answer is 2/5

Step-by-step explanation:

Let the denominator of the fraction be x.

Given that, the numerator of the fraction is 3 less than the denominator.

⇒ Numerator = x - 3

(x-3)/x is the fraction.

Given that, (N+1)/ (D+1) = 1/2

⇒ [(x -3) + 1] / [ x+ 1] = 1/2

⇒ [x - 2] / [ x+ 1] = 1/2

By cross-multiplication, we get:

2(x - 2) = 1(x + 1)

⇒ 2x - 4 = x + 1

⇒ 2x - x = 4 + 1

⇒ x = 5

⇒ Denominator = x = 5

⇒ Numerator = x - 3 = 5 - 3 = 2

Therefore, the required fraction is 2/5.
