Question

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 1

The fraction of students who are now walkers is 2/5.

Step-by-step explanation:

In order to determine the fraction of students who are walkers after their number doubles, we need to first find the initial fraction of walkers.

The question tells us that 20% of Poe M.S. students walk to school, so the initial fraction of walkers is 20/100 or 1/5.

If the number of walkers doubles, the new fraction of walkers will be 2/5.

This is because doubling the number of walkers means they now make up 2 parts out of the total of 5 parts (2 out of 5 equals 2/5).

Therefore, the fraction of the students who are now walkers is 2/5.
