Question

in a friction, the numerator is four more than the denominator if five is added to the numerator the denominator The new friction is 4/3 find the original friction

Answer 1

Let the numerator be x.

Then the denominator will be 2x - 4.

Therefore the fraction will be x/2x - 4    ---------- (1)

Given 5 is added to the numerator and to the denominator and fraction = 4/3.

 (x+5)/(2x - 4 + 5) = 4/3

(x+5)/(2x+1) = 4/3

3x + 15 = 8x + 4

5x = 11

x = 11/5

Substitute x in(1), we get New fraction = 11/5/2(11/5) - 2.
