Answer 2

GiveN:-

• The denominator of a rational number is greater than the numerator by 7.
• If the numerator is increased by 17 and denominator is decreased by 6, the new number becomes 2.

To FinD:-

The original number.

SolutioN:-

Let the original number be x/y.

Let the numerator be x and denominator be (x + 7).

Now if the numerator is increased by 17 and denominator is decreased by 6, the new number becomes 2.

• Numerator = x + 17
• Denominator = (x + 7) - 6

So,

According to the question,

$\large\implies{\sf{\dfrac{x+17}{(x+7)-6}=2}}$

$\large\implies{\sf{\dfrac{x+17}{x+7-6}=\dfrac{2}{1}}}$

$\large\implies{\sf{\dfrac{x+17}{x+1}=\dfrac{2}{1}}}$

By cross multiplying,

$\large\implies{\sf{x+17=2(x+1)}}$

$\large\implies{\sf{x+17=2x+2}}$

$\large\implies{\sf{17-2=2x-x}}$

$\large\implies{\sf{15=x}}$

$\large\therefore\boxed{\bf{x=15.}}$

The number is:-

1. Numerator = 15
2. Denominator = x + 7 = 15 + 7 = 22

Therefore,

The original number is 15/22.
