Question

what is the original number??​

Answer 1

Answer:

12:18

Explanation:

If we have 1:2 adding 1 to both the numerator and denominator the rational number is 2:3.

But 2:3 can’t be the final solution because the numerator + 6 is equal to the denominator. So both have to be multiplied by the same number. We could say that:

(2*x)+6 = 3*x;

Then

x=6;

And

(2*6):(3*6)=12:18

Answer 2

Answer:

(2/8)

Step-by-step explanation:

Let the numerator be x and denominator (x+6)

(x-1)/(x+6-1) = (1/2)

(x-1)/ (x+5) = 1/2

2(x+1) = (x+5)

2x +2 = x+5

2x-x = 5-3

x = 2

The original rational number is 2/ 6+2 i.e (2/8)
