Question

the denominator of a certain fraction is three times the numerator. If 2 is added to the numerator the fraction is equal to 1. what is the original number.

Answer 1

let the numerator be x and the denominator is 3x
put X=1
p(x)=x/3x
p(1)=1/3
if 2 is added to 1
(1+2)/3
=3/3
=1

Answer 2

Answer:

The original fraction is $\frac{1}{3}$

Step-by-step explanation:

Given : The denominator of a certain fraction is three times the numerator. If 2 is added to the numerator the fraction is equal to 1.

To find : What is the original number?

Solution :

Let the numerator be x,

Then the denominator is 3x

Fraction is $\frac{x}{3x}$

According to question,

$\frac{x+2}{3x}=1$

$x+2=3x$

$3x-x=2$

$2x=2$

$x=1$

The numerator is 1 .

The denominator is 3(1) = 3 .

The original fraction is $\frac{1}{3}$
