Adding Mixed Numbers and Fractions

This video tutorial teaches how to add mixed numbers using equivalent fractions. It begins with an introduction to mixed numbers and equivalent fractions, followed by a review of area models and fractions. The video explains improper fractions and common mistakes, then demonstrates creating area models for mixed numbers. It covers adding mixed numbers with like denominators and provides an example of adding mixed numbers with different denominators. The lesson concludes with a summary of the key concepts learned.

What is the first step in adding mixed numbers with like denominators?

• Subtract the smaller fraction from the larger one

• Convert them to improper fractions

• Find a common denominator

• Add the whole numbers first

How is an area model used in understanding fractions?

• It shows the division of a whole into equal parts

• It represents the multiplication of fractions

• It helps in subtracting fractions

• It is used to compare two fractions

What is an improper fraction?

• A fraction where the numerator is smaller than the denominator

• A fraction where the numerator is larger than the denominator

• A fraction with a denominator of one

• A fraction that cannot be simplified

What common mistake is made when converting mixed numbers to improper fractions?

• Placing the whole number in front of the numerator

• Ignoring the whole number

• Adding the denominators

• Multiplying the whole number by the denominator

How do you find the equivalent fraction of a mixed number?

• Subtract the numerator from the whole number

• Add the whole number to the numerator

• Divide the numerator by the denominator

• Multiply the whole number by the denominator and add the numerator

What is the sum of 3 and 1/4 plus 2 and 1/4?

• 5 and 2/4

• 5 and 1/2

• 5 and 1/4

• 5 and 3/4

When adding mixed numbers with like denominators, what do you do after converting them to improper fractions?

• Divide the numerators by the denominators

• Multiply the numerators and denominators

• Subtract the numerators and change the denominator

• Add the numerators and keep the denominator the same

In the example of adding 2 and 1/4 plus 1 and 1/3, what is the first step?

• Add the whole numbers

• Convert to improper fractions

• Find a common denominator

• Subtract the smaller fraction from the larger one

What is the equivalent fraction of 2 and 1/4?

• 10/4

• 8/4

• 9/4

• 7/4

What is the sum of 2 and 1/4 plus 1 and 1/3?

• 3 and 7/12

• 3 and 5/12

• 3 and 11/12

• 3 and 1/12
