Answer:

The rate of text messages per hour is 45 text messages.

Step-by-step explanation:

There are 60 minutes in an hour and you know that 9 text messages are sent every 12 minutes. With this information, you look at the minutes first. Since 12 multiplied with 5 is 60, you can do the same with the 9 and just multiple 9 by 5.

Answer: 45

Step-by-step explanation:

1. [tex]\frac{(9 messages)(60 minutes)}{(12 minutes)(1 hour)}[/tex]

2. 450 messages in 60 minutes divided by 12 minutes equals 45 messages per hour. The "minutes" can be crossed out, which leaves the equation at messages per hour.
