Making Fractions

What is the first thing you do to find a common denominator?

• make them equivalent

• none of the above

Which number do you use for the denominator after you list the multiples of both denominators?

• The largest common multiple

• The least common multiple

• just multiply the denominators

• add the denominators

Why do we make fractions equivalent?

• So we can add or subtract them

• So we can multiply or divide them

• So we can work hard

• So we can get confused
