Looking Back at Your Lesson.

 $\frac{8}{10}\ =\ \frac{4}{5}$  The GCF of 8 and 10 is 2, so  $\frac{8}{10}\ \div\ \frac{2}{2}\ =\ \frac{4}{5}$  

 $\frac{11}{3}\ =\ 3\ \frac{2}{3}$  Change an improper fraction to a mixed number. 11  $\div$  3  $=$  3 with a remainder of 2

 $\frac{30}{30}\ =\ 1$  

 $5\ \frac{2}{6}\ =\ 5\ \frac{2\div2}{6\div2}\ =\ 5\ \frac{1}{3}$   Simplify the fractional part of the mixed number

 $9\ \frac{3}{3}\ =\ 9+1=10\ because\ \frac{3}{3}\ =1$  

 $\frac{24}{36}=\frac{24}{36}\div\frac{12}{12}=\frac{2}{3}\ GCF\ of\ 24\ and\ 36\ is\ 12.$  

 $12\ \frac{15}{9}=?\ GCF\ of\ 15\ and\ 9\ is\ 3.\ \frac{15}{9}\div\frac{3}{3}=\frac{5}{3}=1\ \frac{2}{3}\$
