Question from alex, a student: In a certain fraction the number by n the denominator is greater than the number by3.If 2 is added to both the numerator and denominator ,the fraction is increased by 6/35..Find the fraction. |
Hi Alex,
If the numerator is $n$ and the denominator is 3 more than the denominator, then the denominator is $n + 3$ and the fraction is then $\large \frac{n}{n + 3}.$
If you add 2 to each of the numerator and denominator what fraction do you get? This fraction is $\large \frac{6}{35}$ larger than $\large \frac{n}{n + 3}.$ Solve for $n.$
