Comparing Fractions Using the Butterfly Method

The video tutorial explains how to compare fractions using the butterfly method, also known as the cross-multiply method. It provides three examples: comparing 2/8 with 3/5, 6/7 with 2/9, and 1/2 with 4/8. The method involves cross-multiplying the numerators and denominators to easily determine which fraction is greater, less than, or equal to the other.

What is the primary method discussed for comparing fractions?

• Butterfly method

• Decimal conversion

• Finding common denominators

• Using a calculator

In the butterfly method, what is the first step when comparing two fractions?

• Add the fractions

• Subtract the fractions

• Cross-multiply the denominators

• Cross-multiply the numerators

What is the result of cross-multiplying 8 and 3 in the example of 2/8 and 3/5?

• 16

• 40

• 24

• 10

After cross-multiplying, what do you compare to determine which fraction is larger?

• The original fractions

• The numerators

• The cross-multiplied results

• The denominators

What is the result of comparing 10 and 24 in the first example?

• 10 is not comparable to 24

• 10 is less than 24

• 10 is equal to 24

• 10 is greater than 24

In the example of 6/7 and 2/9, what is the result of 7 times 2?

• 16

• 12

• 18

• 14

What is the result of 9 times 6 in the second example?

• 36

• 63

• 45

• 54

What is the result of comparing 54 and 14 in the second example?

• 54 is not comparable to 14

• 54 is greater than 14

• 54 is equal to 14

• 54 is less than 14

In the third example, what is the result of 2 times 4?

• 12

• 6

• 8

• 10

What is the result of 8 times 1 in the third example?

• 12

• 6

• 8

• 10
