Question

It takes Pam 45 minutes to drive to work in 16 minutes to drive home from work right the ratio of the time Pam spends driving home from work in the time she spends driving to work in three different ways

Answer 1

When you write a ratio, you can write it many different ways, but an easy way to start is the following:
a:b
Where a and b are numbers.

So in your problem you would write the number (in minutes) that it takes her to drive home : the time it takes for her to go to the work.

Does that make sense?
Do you know any other ways to write a proportion?
