The numerator of a fraction (which is in its simplest form) is 5 less than the denominator. If the numerator is multiplied by 2, and the denominator is increased by 16, then the fraction becomes smaller by 1 3 of it. Find the original fraction.

Answer:

The original fraction is [tex]\frac{3}{8}[/tex]

Step-by-step explanation:

Let the denominator be x

We are given that The numerator of a fraction (which is in its simplest form) is 5 less than the denominator.

Numerator = x-5

So, Fraction =[tex]\frac{x-5}{x}[/tex]

If the numerator is multiplied by 2, and the denominator is increased by 16, then the fraction becomes smaller by 1\3 of it.

A.T.Q

[tex]\frac{2(x-5)}{x+16}=\frac{2(x-5)}{3x}[/tex]

[tex]\frac{2x-10}{x+16}=\frac{2x-10}{3x}[/tex]

[tex]3x=x+16[/tex]

[tex]2x=16[/tex]

x=8

Denominator = 8

Numerator = x-5=8-5=3

Fraction : [tex]\frac{3}{8}[/tex]

Hence the original fraction is [tex]\frac{3}{8}[/tex]
