Adding Fractions with Unlike Denominators

The video tutorial explains how to add fractions with different denominators by converting them to have the same denominator. It demonstrates converting 2/3 to a fraction with a denominator of 9, then adding it to 4/9. The result is an improper fraction, 10/9, which is then converted to a mixed number, 1 and 1/9. The tutorial emphasizes understanding the relationship between numerators and denominators and provides two possible answers: an improper fraction and a mixed number.

Why is it important to have the same denominator when adding fractions?

• To ensure the fractions can be added directly

• To convert them into whole numbers

• To simplify the fractions

• To make the numerators equal

What is the result of converting 2/3 into a fraction with a denominator of 9?

• 6/9

• 4/9

• 2/9

When adding 4/9 and 6/9, what is the resulting fraction?

• 12/9

• 10/9

• 8/9

• 9/9

What is an improper fraction?

• A fraction that cannot be simplified

• A fraction where the numerator is equal to the denominator

• A fraction where the numerator is larger than the denominator

• A fraction where the numerator is smaller than the denominator

How can the improper fraction 10/9 be expressed as a mixed number?

• 1 and 3/9

• 1 and 2/9
