The video tutorial explains how to add fractions with unlike denominators using number lines. It begins by illustrating the problem of adding fractions with different denominators and then demonstrates how to find a common denominator by dividing a number line into equal parts. The tutorial shows how to represent fractions as equivalent fractions with a common denominator and then adds them using a number line. The lesson concludes with a summary of the process and the result of adding the fractions.

Why can't fractions with different denominators be directly added?

• They are already in simplest form.

• They are not real numbers.

• They are always improper fractions.

• They represent different sized parts.

What happens when you try to represent 1/2 and 2/3 on a number line divided into 4 parts?

• Neither fraction can be represented.

• Only 2/3 can be represented.

• Only 1/2 can be represented.

• Both fractions can be represented.

Which division of the number line allows both 1/2 and 2/3 to be represented?

• 7 parts

• 4 parts

• 5 parts

• 6 parts

What is the equivalent fraction of 1/2 when the number line is divided into 6 parts?

• 2/6

• 3/6

• 4/6

• 5/6

What is the result of adding 1/2 and 2/3 using a common denominator?

• 8/6

• 5/6

• 6/6

• 7/6
