for the 1st problem, start by factoring the numerators and denominators of both fractions ... then do the division by multiplying by the reciprocal of the divisor.
The problem child I scanned...
(Note: The scanner cut off part of the problem, thats a 4 on the left side there.)
While I work on correcting some problems, this was another one from earlier I was having problems with. Anyone know the right way to solve it?
This should also be the last problem for now I ask for steps on how to do it. (Until I possibly stumble upon another one later...)
I also forgot to post this earlier, its 2 other problems I wanted to check on if I did it right (if I didn't please point out where). Although i'm now noticing I didn't quite finish #2 yet, but am I at least on the right track?
More children with problems...
