Chapter 4: Dividing Fractions

Multiple Select

Select all the expressions that represent a value greater than 1.

• $$4\div\frac{2}{3}$$  

• $$\frac{3}{4}\div\frac{2}{3}$$  

• $$\frac{14}{8}\div\frac{15}{8}$$  

• $$2\frac{4}{8}\div1\ \frac{5}{8}$$  

• $$\frac{1}{5}\div4$$  

​We can use diagrams to help us solve other division problems that require finding a fraction of a group.

​

This is a diagram to help us answer the question:

“What fraction of 9/4  is 3/2 ?,” which can be written as 3/2 ÷ 9/4 .
