Adding Mixed Numbers Using Fraction Bars

This video tutorial teaches how to add mixed numbers using fraction bars. It begins with a review of equivalent fractions and common denominators, then demonstrates how to add fractions with common denominators. The tutorial addresses common misunderstandings and shows how to decompose mixed numbers into fractional parts. It explains how to find equivalent fractions for addition and concludes with a final addition example.

What is the first step in adding mixed numbers using fraction bars?

• Multiply the fractions

• Subtract the fractions

• Find a common denominator

• Find a common numerator

Why is it incorrect to add 1 1/2 and 2 1/3 directly without forming common denominators?

• Because the fractions are already simplified

• Because the whole numbers are not equal

• Because the fractions have different numerators

• Because the fractions have different denominators

How can you decompose 1 1/2 into fractional parts?

• As 1/2 and 1/3

• As 1/2 and 2/3

• As 3/2

• As 2/3

What is the purpose of multiplying by 1 when finding equivalent fractions?

• To change the value of the fraction

• To simplify the fraction

• To keep the value of the fraction unchanged

• To make the fraction improper

What is the final sum of 1 1/2 and 2 1/3 when added correctly?

• 3 and 2/5

• 3 and 1/2

• 3 and 5/6

• 3 and 1/3
