 $\frac{2}{3}$  and  $\frac{3}{4}$  

Find the LOWEST COMMON DENOMINATOR for the pairs of fractions given. Rewrite the fractions as equivalent fractions with the LOWEST COMMON DENOMINATOR. 

 $\frac{4}{5}$  and  $\frac{7}{15}$  

Find the LOWEST COMMON DENOMINATOR for the pairs of fractions given. Rewrite the fractions as equivalent fractions with the LOWEST COMMON DENOMINATOR. 

Which strategy describes how to find a common denominator.

• If both denominators are a multiples of each other, the higher denominator is the lowest common denominator.

• List the multiples of both denominators until you come to the lowest multiple they both have in common. This is your LCD.

• List equivalent fractions until you come to the set of equivalent fractions that have common denominators.

• All the above.
