Mixed VS Improper Adding Fractions

The video tutorial explains how to add mixed numbers using two approaches: the mixed number approach and the improper fraction approach. The instructor discusses the benefits and challenges of each method, emphasizing the importance of converting back to mixed numbers if the problem started with them. The tutorial provides a step-by-step guide on both methods, highlighting the need for finding common denominators and the potential for confusion with mixed numbers. The instructor concludes by encouraging viewers to be comfortable with both approaches and to choose based on the problem or teacher's instructions.

What is one advantage of using the mixed number approach when adding mixed numbers?

• It preserves the mixed number format, simplifying the problem.

• It always results in smaller numbers.

• It is the only method taught in schools.

• It eliminates the need for common denominators.

When adding mixed numbers, what is the first step according to the mixed number approach?

• Convert them to improper fractions.

• Find the least common multiple of the denominators.

• Add the fractional parts first.

• Add the whole numbers first.

Why is it important to find a common denominator when adding fractions?

• To accurately add the fractions together.

• To convert them into whole numbers.

• To make the fractions improper.

• To ensure the fractions are in simplest form.

What is the result of adding 1/3 and 2/5 after finding a common denominator?

• 11/15

• 3/5

• 21/15

• 7/8

How do you convert a mixed number to an improper fraction?

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

• Subtract the numerator from the whole number.

• Add the whole number to the numerator.

• Multiply the numerator by the denominator.

What should you do after obtaining an answer in improper fraction format?

• Add it to the original mixed number.

• Multiply it by the denominator.

• Convert it back to a mixed number.

• Leave it as it is.

What factor should influence your choice of method for adding mixed numbers?

• The size of the numbers involved.

• The instructions given by your teacher.

• The time of day.

• The color of the numbers.
