Question

3. WALLPAPER The design on Santana's wall includes 16 pink stripes and 20 green stripes. Find the ratio of pink stripes to green stripes.

Answer 1

When we are calculating a ratio between two things, there are two important things: the amount of each, and the order in which they are mentioned.

Since in this case we have:

Pink stripes: 16

Green stripes: 20

and the order in which they are mentioned for the ratio is "pink stripes to green stripes", we will put the pink stripes first. And the ratio is:

`16\colon20`

This ratio can be simplified. Since both 16 and 20 are divisible by 4:

16/4 = 4

20/4 = 5

We can use 4 and 5, for the simplified ratio
