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, building equivalent fractions, and simplifying improper fractions to reach the final answer.

What is the first step when adding mixed numbers with the same denominators?

• Convert to improper fractions

• Add the numerators

• Add the integers

• Find the least common denominator

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

• 15

• 20

• 10

• 5

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

• Multiply both numerator and denominator by 4

• Multiply both numerator and denominator by 5

• Multiply both numerator and denominator by 3

• Multiply both numerator and denominator by 2

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

• 13 and 19/15

• 14 and 4/15

• 13 and 4/15

• 14 and 19/15

What should you ensure about the denominators when adding mixed numbers?

• They are prime numbers

• They are different

• They are even numbers

• They are the same
