The original number is 15/22.

## ExPlanation:

Let numerator be x.

So, the denominator will be x+7.

According to the question,

• If numerator is increased by 17 = x+17

• When denominator is decreased by 6=x+7-6=x+1.

Then the above value must be equal to 2.

So, So ,the value of numerator will be x= 15.

Now as per given conditions,

• Denominator is greater than its numerator by 7.

So, So, the fraction is Original no. is fraction which is 2. • The denominator of a rational number is greator thqn its numerator by 7. If the numerator is increased by 17 and the denominator is decreased by 6 the new number becomes 2. Find the original number ✏ let the numerator be x

✏ therefore denominator = x + 7

### Given:–

✏ numerator increased by 17 = x + 17

✏ denominator decreased by 6 = x + 7 – 6

denominator = x + 1 ### Explanation:– • cross multiplication
