Question

To get to your school 2/5 of the students walk, 1/3 of the students ride the bus, and the rest come in cars. How many students come to school in cars?

Answer 1

Let `1` represent all of the students. You can solve this by creating a common denominator for all fractions:

`1-2/5-1/3`
`15/15-6/15-5/15`
`(15-6-5)/15`
`4/15`

`4/15` of the students come in cars.
