Britney just got a new video game for her birthday. Yesterday, she played for 27 minutes and beat 3 levels. Today, her parents said she can play for 45 minutes. If she beats levels at the same rate, how many levels should Britney beat today?

5 levels

Step-by-step explanation:

To know the rate of her beating levels yesterday, divide the # of minutes she played (27 minutes) to the # of levels she beat (3 levels).

So she played for 9 minutes to beat a single level.

Since she will try to beat levels the same rate as yesterday, you will have to divide the #of minutes her parents let her play (45 minutes) to yesterday's rate (9 minutes per level).

Britney should beat 5 levels today if she wants to beat levels at the same rate as yesterday's.
