Thread: find the value of the fraction..

A given fraction has a value of 3/8. find the value of this fraction, such that when 43 is added to both its numerator and denominator, will result to a new fraction of value 4/9..


can anybody check my work... please


do i have to add 3 + 4 / 8 + 4 = 7/12? what will i do with 4/9? thanks
please do me a favor...

N = Numerator
D = Denominator






Compare this very carefully to the text of the problem statement.

It comes from the problem statement.

i still couldn't figure out the fraction

First, determine what N is in terms of D as follows:

Then you use the other equation to solve for D, and put the fraction in instead of N, like this:


Then when you have D, you just use the value you get for D to solve for N.
