Reducing Fractions Before Multiplying

The video tutorial explains how to multiply fractions using two methods. The first method involves multiplying the numerators and denominators directly and then reducing the result. The second method simplifies the fractions by canceling common factors before multiplying, which eliminates the need for further reduction. The tutorial provides examples to illustrate both methods, emphasizing the importance of identifying common factors to simplify calculations.

What is the first step in the initial method of multiplying fractions?

• Add the numerators and denominators

• Multiply the numerators and denominators

• Subtract the numerators from the denominators

• Divide the numerators by the denominators

After multiplying the numerators and denominators, what should you do next?

• Leave the result as it is

• Add the results

• Reduce the fraction

• Multiply by another fraction

In the second method, what is done before multiplying the fractions?

• Add the fractions

• Cancel and reduce common factors

• Subtract the fractions

• Multiply the fractions directly

Which numbers can be reduced in the example of the second method?

• 5 and 7

• 5 and 8

• 2 and 8

• 2 and 7

What is the final result of the example using the second method?

• 2/3

• 1/4

• 10/56

• 5/28

In the example of reducing before multiplying, which numbers are reduced first?

• 11 and 22

• 3 and 9

• 5 and 12

• 3 and 20

What is the final reduced answer in the example of reducing before multiplying?

• 1/2

• 2/3

• 3/4

• 5/6

In the last example, which pair of numbers is reduced first?

• 5 and 12

• 3 and 20

• 5 and 20

• 3 and 12

What is the final result of the last example?

• 1/4

• 1/16

• 1/8

• 1/2

What is the benefit of reducing fractions before multiplying?

• It makes the numbers larger

• It simplifies the calculation

• It adds more steps

• It makes the result incorrect
