Eureka Module 5 Topic B Review grade 4

This model has been decomposed. Find the multiplication equation that represents the decomposition.

• $\frac{3}{4\ }\div\frac{3}{3\ }=\frac{1}{12}$

• $\frac{3}{4}=\frac{3}{4}\times\frac{4}{4}=\frac{12}{16}$

• $\frac{3}{4}=\frac{3}{4}\times\frac{3}{3}=\frac{9}{12}$

 $Find\ all\ of\ the\ fractions\ that\ are\ equivalent\ to\frac{2}{3}.$  

•  $\frac{2}{3}=\frac{2}{3}\times\frac{2}{2}=\frac{4}{6}$  

•  $\frac{2}{3}=\frac{2}{3}\times\frac{3}{2}=\frac{6}{6}$  

•  $\frac{2}{3}=\frac{2}{3}\times\frac{3}{3}=\frac{6}{9}$  

•  $\frac{2}{3}=\frac{2}{3}\times\frac{4}{4}=\frac{8}{12}$  

 $\frac{2}{6}=\frac{2}{6}\times\frac{ }{ }=\frac{8}{ }$  Fill in the missing information to make the fractions equivalent.

•  $\frac{3}{3}\ \ \ \ \frac{8}{18}$   

•  $\frac{4}{3}\ \ \ \ \ \ \frac{8}{18}$  

•  $\frac{2}{2}\ \ \ \frac{8}{12}$  

•  $\frac{4}{4}\ \ \ \ \ \frac{8}{24}$  

 $Find\ an\ equivalent\ fraction\ for\ \frac{3}{4}.$  

 $Which\ fraction\ is\ equivalent\ to\ \frac{2}{4}?$  

•  $\frac{6}{12}$  

•  $\frac{1}{3}$  

•  $\frac{4}{6}$  

•  $\frac{2}{8}$  

Santerica drew a number line from 0 to 1. She partitioned the number line into thirds and then decomposed 1/3 into 4 equal lengths. Which number sentence shows how Santerica could use multiplication to show which fraction is equivalent to 1/3?

• $\frac{1}{3}=\frac{1}{3}\times\frac{2}{2}=\frac{2}{6}$

• $\frac{1}{3}=\ \frac{1}{3}\times\frac{4}{4}=\frac{4}{12}$

• $\frac{1}{3}=\frac{1}{3}\times\frac{3}{1}=\frac{3}{3}$

The ______________________ is the top of a fraction and tells what part of the whole is shaded.

True or False? When multiplying to decompose a fraction, the numerator and denominator have to be multiplied by the same number.

Lily Rose wants to divide to find an equivalent fraction. She used Santerica's number line. Which number sentence shows how LIly Rose divided to find a fraction equivalent to 1/3?

• $\frac{4}{12}=\frac{4}{12}\div\frac{4}{4}=\frac{1}{3}$

• $\frac{4}{12}=\ \frac{4}{12}\div\frac{2}{2}=\frac{2}{6}$

• $\frac{8}{12}=\frac{8}{12}\div\frac{4}{4}=\frac{1}{3}$

How do you know that 1/3 is equivalent to 4/12?
