Understanding the Butterfly Method for Subtracting Fractions

The video tutorial explains the butterfly method for subtracting fractions. It provides two examples, detailing each step of the calculation process. The first example results in a fraction that cannot be simplified further, while the second example demonstrates simplification by finding a common factor. The tutorial emphasizes the importance of simplifying fractions to their lowest terms.

What is the first step in the butterfly method for subtracting fractions?

• Cross-multiply the numerators and denominators

• Multiply the numerators together

• Multiply the denominators together

• Add the fractions

In the first example, what is the result of 7 times 3?

• 21

• 10

• 28

• 14

What is the simplified form of the fraction 13/28?

• 1/2

• 13/28

• 3/4

• 5/6

In the second example, what is the result of 6 times 7?

• 48

• 42

• 30

• 36

What is the final simplified form of the fraction 32/60?

• 4/5

• 8/15

• 5/8

• 2/3
