Add Mixed Numbers

The video tutorial explains how to add mixed numbers, starting with those having like denominators and then moving to those with unlike denominators. It covers finding the least common denominator (LCD) and building equivalent fractions. The tutorial also demonstrates how to simplify improper fractions to arrive at the final answer.

What is the first step in adding mixed numbers with the same denominator?

• Add the denominators

• Add the integer parts

• Add the numerators

• Convert to improper fractions

What is the least common denominator (LCD) of 5 and 3?

• 10

• 20

• 5

• 15

How do you convert the fraction 3/5 to have a denominator of 15?

• Multiply both numerator and denominator by 2

• Multiply both numerator and denominator by 3

• Multiply both numerator and denominator by 5

• Multiply both numerator and denominator by 4

What is the result of adding 5 and 9/15 to 8 and 10/15?

• 14 and 4/15

• 13 and 19/15

• 14 and 19/15

• 13 and 4/15

What should you do if the result of adding fractions is an improper fraction?

• Subtract from the denominator

• Convert it to a mixed number

• Leave it as it is

• Add more to the numerator
