Adding Mixed Numbers

The Associative Property of the Addition allows us to group the whole number and group the fractions to add easily!

Multiple Select

 $Which\ of\ these\ is\ equal\ to\ 7\ \frac{5}{8}?$  

•   $6\ \frac{1}{8}+1\ \frac{4}{8}$  

•  $3\ \frac{1}{8}+4\ \frac{3}{8}$  

•  $5\ \frac{4}{8}+2\ \frac{6}{8}$  

Subtracting Mixed Numbers

When the first fraction is smaller than the second fraction, remember you need to regroup!
