Answer 2

Answer:

The fraction is 3/4.

Explanation:

Given that :

Numerator + Denominator = 7

Denominator = 7 - Numerator

Let the Numerator be x.

∴ Denominator = (7 - x)

Also, Four times the numerator is 8 less than 5 times the denominator.

⇒ 4(x) = 5(7 - x) -8

⇒ 4x =  35 -5x -8

⇒ 4x = 27 - 5x

⇒ 4x + 5x = 27

⇒ 9x = 27

⇒ x = 3

Therefore, the fraction is x / 7-x i.e. 3/4.
