Mastering Fraction Simplification for Multiplication

The video tutorial explains how to simplify fractions before multiplying them to make the process easier. It provides several examples, demonstrating how to reduce fractions by dividing both the numerator and the denominator by the same number. The tutorial also covers how to handle whole numbers in fraction multiplication and offers practice problems for viewers to solve on their own.

What is the first step in simplifying the fraction 9/15 * 4/8?

• Reduce 9/15 to 3/5.

• Reduce 4/8 to 1/2.

• Cross multiply the fractions.

• Multiply the numerators and denominators directly.

After simplifying 9/15 and 4/8, what is the resulting fraction before multiplication?

• 9/15 * 4/8

• 3/5 * 4/8

• 3/5 * 1/2

• 9/15 * 1/2

In the second example, what common factor is used to simplify 51/85?

• 3

• 5

• 17

• 9

Why is it beneficial to simplify fractions before multiplying?

• All of the above.

• It avoids the need for division later.

• It ensures the answer is in lowest terms.

• It makes the multiplication process faster.

What is the simplified form of 3/34 * 17/15?

• 1/10

• 3/10

• 1/5

• 3/5

How do you handle a whole number in fraction multiplication?

• Add it to the numerator of the other fraction.

• Ignore it and multiply the other fractions.

• Convert it to a fraction by placing it over 1.

• Convert it to a decimal.

What is the simplified result of 3/34 * 4?

• 6/17

• 3/17

• 1/17

• 1/4

In the practice problem 14/15 * 5/8, what is the simplified form of 14/8?

• 14/4

• 7/8

• 14/8

What is the final answer for the practice problem 2 1/2 * 4/5?

• 1

• 1/2

• 5/2

• 2

Why does the process of simplifying fractions before multiplying only work for multiplication?

• Because it involves division of common factors.

• Because addition and subtraction require different rules.

• Because multiplication is commutative.

• All of the above.
