Answer» ct half way point would be 4.5 /9, which is very hard to DEAL with.In order to MAKE this simpler to UNDERSTAND. Let's do this the EASY way.Change 4/9 to 8 /18.(Do this by MULTIPLYING the top and bottom of the fraction by 2.)Change 5/9 to 10/18.(Do this by multiplying the top and bottom of the fraction by 2.)Now we want the midpoint of 8/18 and 10/18. That would be 9/18.This can be reduced to 1/2.
