Adding and Subtracting Fractions with Unlike Denominators

The video tutorial explains how to add and subtract fractions with different denominators. It uses relatable examples to illustrate the concept of needing like denominators, similar to not being able to add apples and oranges. The tutorial employs area models to visually demonstrate how to create equivalent fractions, making it easier to perform addition and subtraction. The process involves adjusting the fractions to have the same denominator before performing the arithmetic operations.

Why can't you directly add 1 apple and 3 oranges?

• They are the same size.

• They are different types of fruit.

• They have different colors.

• They are both fruits.

What must be done before adding fractions with different denominators?

• Add the denominators.

• Subtract the smaller fraction.

• Multiply the numerators.

• Find a common denominator.

In the example of adding 1/2 and 1/4, what is the equivalent fraction of 1/2?

• 1/4

• 2/4

• 4/4

• 3/4

What is the result of adding 1/2 and 1/4?

• 1/4

• 1

• 1/2

• 3/4

When subtracting 3/8 and 1/4, what is the equivalent fraction of 1/4?

• 3/8

• 2/8

• 1/8

• 4/8

What is the result of subtracting 3/8 and 2/8?

• 1/8

• 4/8

• 2/8

• 3/8

What is the key step in both adding and subtracting fractions with different denominators?

• Ignoring the denominators.

• Finding equivalent fractions with the same denominator.

• Multiplying the fractions.

• Dividing the fractions.
