Answer:
120
Explanation:
This method works for any unit rate problem.
I am using the first rate for simplicity.
A unit rate always has a 1 for the numerator.
Convert 2/240 so that it had a 1 for the numerator instead of a 2.
2 divided by 2 is 1.
240 divided by 2 is 120.
120 is your answer.
Why divide 240 by 2?
To get 2 to 1, you need to divide the 2 by 2.
Anything you do to the numerator, (2) you need to do to the denominator (240).
