Problem:Javia ran 8 laps around a track to run a total of 1 mile on Monday. How many laps will she need to run on Tuesday to run 3/8 of a mile?Question:How will you use what you know about number lines to help you solve this problem?

Answer :

1 mile ---- 8 laps

3/8 mile ---- x laps

x is the number of laps to run 3/8 miles

[tex]x=\frac{\frac{3}{8}\cdot8}{1}=\frac{3}{1}=3[/tex]

3 laps to run 3/8 miles

In order to answer that with a number of lines, we can divide each mile into 8 parts each part represent a lap

the line in red represent the 8 laps in 1 mile

the line in blue represent the 3 laps 3/8 mile
