Looking Back at Your Lesson.

Looking Back at Your Lesson.

From your previous lesson, you have learned about simplifying fractions. Simplifying fractions is sometimes called reducing fractions to its lowest terms. The fraction is in its simplest form when the GCF of the numerator and denominator is 1. Let us simplify these fractions:

•  $\frac{8}{10}\ =\ \frac{4}{5}$  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}\$  

   $12+1\ \frac{2}{3}\ =\ 13\ \frac{2}{3}$
