Question 1149747: Twenty percent of Poe M.S. students walk to school. If the number of "walkers" doubles, and there is no change in the number of non-walkers, what fraction of the students are now walkers? Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! 20% walkers, or 1/5, is a ratio of [ 1 walker ] / [ 4 non-walkers ]
Now double the number of walkers
[ 2 walkers ] / [ 4 non-walkers ]
As a fraction of all the students, this is:
1/3 of the students are now walkers
