Apply It: Multiplying Fractions in Unit Form
In “Bye-Bye, Bao Bao!” (pages 4-7), you multiplied fractions to learn more about pandas.
When solving these types of problems, try using unit form or drawing a model. Try it with
the questions below.
Unit form: Expressing a number using its place value or fractional value as a unit. For example,
expressing
1
10
in unit form would be 1 tenth.
