There are several ways to do this. My way may not be the correct "math" way but then I am NOT a math teacher!
3/4 = 6/8. do you see why? If one finished 1/4 more, that is the same as saying 2/8. Subtract 2 from 6 and that leaves 4/8 (which is the same, by the way, as 2/4 or 1/2. Divide that in 2 and each girl finished 2/8 (or 1/4) = 4/8 (1/2) leaving the 2/8 (1/4) extra of the one girl.
I'm sure a math teacher will explain all this much better, if this is not clear to you!
