Add & Subtract Fractions

Vanna used the fraction strips shown to help her determine the difference between  $\frac{5}{6}$  and  $\frac{1}{4}$  .


What is   $\frac{5}{6}-\frac{1}{4}$  ?

•  $\frac{1}{5}$  

•  $\frac{7}{12}$  

•  $\frac{1}{2}$  

•  $\frac{5}{8}$  

The shaded part of the model represents a fraction. Another fraction was subtracted from the first fraction.

Which expression does the model represent?

• $\frac{11}{15}-\frac{1}{6}$

• $\frac{11}{12}-\frac{6}{12}$

• $\frac{6}{15}-\frac{4}{15}$

• $\frac{11}{15}-\frac{2}{5}$

Cara and Marcus shared a candy bar. The models are shaded to show the fraction of the candy bar each of them ate.

What fraction of the candy bar did Cara and Marcus eat altogether?

• $\frac{11}{12}$

• $\frac{9}{16}$

• $\frac{1}{12}$

• $\frac{9}{24}$

Anne is making a quilt. She made  $\frac{1}{4}$  of the quilt yesterday, and she made  $\frac{3}{8}$  of the quilt today. Choose the quilt that represents how much of the quilt she has made. The gray represents the amount she has made.

Newspaper advertisements can be  $\frac{1}{4}$  of a page,  $\frac{1}{2}$  of a page, or a full page. The shaded parts of the model show the fractions of a page used for two advertisements.

Which of the following equations represents the total fraction of the page used for these two advertisements?

•  $\frac{1}{3}+\frac{1}{3}=\frac{2}{3}$  

•  $\frac{1}{4}+\frac{1}{2}=\frac{3}{4}$  

•  $\frac{1}{4}+\frac{3}{4}=\frac{2}{4}$  

•  $\frac{1}{2}+\frac{1}{2}=\frac{4}{4}$  

Solve the following equation and simply/reduce if needed.
 $\frac{2}{3}+\frac{1}{5}$  

•  $\frac{13}{15}$
