CCSS.8.G.A.3

A ratio shows the relative sizes of two or more values.

Ratios can be shown in different ways:
1. using the ":" to separate example values
2. using the "/" to separate one value from the total
3. as a decimal, after dividing one value by the total
4. as a percentage, after dividing one value by the total

Which of these best represents you?

• I totally remember how to use ratios

• I remember being taught what a ratio is, but I can't remember how to use them.

• I think that seems familiar but I can't remember from where and don't remember how to do that.

• What on earth is that talking about?!
