Tips

Remind students that ratios can be written as a fraction, but unlike regular fractions, which only compare a part relative to its whole, a ratio can compare a part to its whole or a part to another part.

Students sometimes assume that the denominator in a ratio is the quantity of the whole, when it may be another part.

Have students work together to correct each other’s work
