Find the rational number.​

Answer 1

Answer: 10/18

Step-by-step explanation:

Let the numerator be x then, denominator or = x + 8

ATQ : by increasing or by decreasing we get

=> x + 17/ x + 8 – 1

=> x +17/ x +7

Hence x = 17–7 = 10

So numerator = x = 10

and denominator = (x+8) = 18

Therefore the fraction = 10/18
