Comparing and Creating Fractions

The video tutorial covers lesson six on comparing and ordering fractions. It introduces the concept of using least common multiples to compare fractions with different denominators and numerators. The lesson includes practical examples, such as comparing insect lengths and cooking times, and provides exercises for students to practice these skills. The tutorial also includes problem-solving scenarios and homework exercises to reinforce learning.

What is the first step in comparing fractions with different denominators?

• Find the greatest common factor.

• Add the fractions together.

• Subtract the smaller fraction from the larger one.

• Find the least common multiple.

How can you create equivalent fractions with the same denominator?

• Add the same number to both the numerator and denominator.

• Multiply both the numerator and denominator by the same number.

• Divide the numerator by the denominator.

• Multiply the numerator by the denominator.

In the example comparing a mosquito and a whirligig beetle, what is the least common multiple of their denominators?

• 16

• 12

• 4

• 8

When ordering cooking times, what is the common numerator used for the equivalent fractions?

• 10

• 5

• 15

• 20

Which fraction is greater: 3/4 or 1/2?

• 3/4

• 1/2

• They are equal

• Cannot be determined

In the problem-solving section, which meat makes up the most of Mr. Collins's sandwich?

• Turkey

• They are all equal

• Ham
