Question

Michelle divides her study time in a 3:1 ratio. How much time in hours does michelle spend studying in a 3 hour period?

Answer 1

Let x represent one ration of time.

 

3 parts to 1 part makes 4 parts

 

3x + x = 3 hours

 

4x = 3 hours

 

x = 3/4

 

So each ration of time is 3/4 hour = 45 minutes.

 

So she divides her study time in 2 hour 15 minutes, then 45 minutes

Answer 2

Michelle divides 180 minutes (3 hours) into four sessions.

How many minutes in each session?
