Allison and Megan were at track practice. The track is 3/8 kilometers around.

Ad libitum [116K]

Allison ran 3/8 km (0.375 km) in 3 minutes.

Set up a proportion to find how long it takes for her to run 1 km

$\frac{0.375\textrm{km}}{3 \textrm{min}} = \frac{1\textrm{km}}{x \textrm{min}}$

Cross multiply to get:

$3 = 0.375x$

Solve:

$x = \frac{3}{0.375}$

x = 8 minutes

Step-by-step explanation:

For a number to be divisible by 4 you just need to worry about the 10s and 1s place. You also want to know that the 1s cylce every 20, or in other words:

4 8 12 16 20

24 28 32 36 40 and so on. So the only numbers that x can be there are 1, 3, 5, 7, 9. Does that make sense? and can you manage the rest?
