Fractions

Multiple Choice

Were the shaded parts of the fractions...

• $\frac{3}{4}>\frac{7}{8}$

• $\frac{3}{4}=\frac{7}{8}$

• $\frac{3}{4}<\frac{7}{8}$

Multiple Choice

Were the shaded fractions...

• $\frac{2}{5}<\frac{4}{10}$

• $\frac{2}{5}>\frac{4}{10}$

• $\frac{2}{5}=\frac{4}{10}$

Multiple Choice

Which of these is the shaded fraction?

• $\frac{3}{5}=\frac{7}{15}$

• $\frac{3}{5}<\frac{7}{15}$

• $\frac{3}{5}>\frac{7}{15}$

Multiple Choice

 $\frac{1}{3}=\frac{6}{12}$  

• True 

• False

Multiple Choice

 $\frac{3}{7}=\frac{7}{21}$  

• True

• False

Multiple Choice

Which fraction is equivalent to

 $\frac{2}{3}$  

•  $\frac{4}{6}$  

•  $\frac{7}{12}$  

•  $\frac{7}{21}$  

ADDING FRACTIONS

If fractions have the same denominator we can just add the numerators together to get the answer.

 $\frac{4}{10}+\frac{2}{10}=\frac{6}{10}$  

Multiple Choice

 $\frac{7}{21}+\frac{5}{21}$  

•  $\frac{13}{42}$  

•  $\frac{13}{21}$  

•  $\frac{7+5}{42}$  

Multiple Choice

 $\frac{1}{7}+\frac{2}{7}$  

•  $\frac{3}{7}$  

•  $\frac{3}{14}$  

The same rules apply for subtracting fractions.

 $\frac{15}{21}-\frac{6}{21}=\frac{9}{21}$  

Multiple Choice

 $\frac{29}{30}-\frac{10}{30}$  

• 19

•  $\frac{19}{30}$  

•  $\frac{1}{2}$  

ADDING OR SUBTRACTING FRACTIONS WITH DIFFERENT DENOMINATORS

First we need make the denominators the same example:

 $\frac{3}{12}+\frac{1}{6}=\frac{3}{12}+\frac{2}{12}=\frac{5}{12}$  

Multiple Select

 $\frac{1}{3}+\frac{4}{6}=$  

• 1

•  $\frac{6}{6}$  

•  $\frac{5}{9}$  

Multiple Choice

 $\frac{6}{18}-\frac{1}{6}=$  

•  $\frac{3}{18}$  

•  $\frac{5}{12}$  

•  $\frac{8}{18}$
