Question

Lucas lives 5/8 mile from school. Kenny lives twice as far as Lucas from school. How many miles does Kenny live from school?

Answer 1

Kenny lives `1 1/4m` from school

Explanation:

First, let miles`=m`

So we can say:

Lucas lives `5/8m` from school

Therefore:

Kenny lives `2xx5/8m` from school

Now we can apply the operation in Kenny's expression:

`2xx5/8m`

`= (2xx5)/8m`

`=10/8m`

This fraction can then be simplified:

`10/8m`

`=(10÷2)/(8÷2)m`

`=5/4m`

It is normally preferred to write improper fractions as mixed numbers, so:

`5/4m`

`=4/4m+1/4m`

`=1 1/4m`
