Comparing Fractions and Equivalent Fractions

This video tutorial covers lesson 18, session two, focusing on comparing fractions using common numerators and denominators. It includes examples of comparing fractions with different denominators, using models to visualize fractions, and finding equivalent fractions. The lesson also provides practice exercises for students to apply their understanding of these concepts.

What is the main focus of this lesson on comparing fractions?

• Understanding improper fractions

• Using bar models to compare fractions

• Learning about decimal fractions

• Comparing fractions using common numerators and denominators

In the example given, which insect weighs more?

• The grasshopper

• The beetle

• Both weigh the same

• Cannot be determined

Why is it easier to compare fractions when they have a common denominator?

• It makes the fractions look similar

• It allows for direct comparison of numerators

• It simplifies the fractions

• It changes the value of the fractions

How do you find an equivalent fraction with a numerator of 8 for two one-hundredths?

• Multiply both numerator and denominator by 2

• Divide the denominator by 2

• Multiply both numerator and denominator by 4

• Add 6 to the numerator

When comparing fractions with the same numerator, which fraction is greater?

• The one with the larger denominator

• The one with the smaller denominator

• The one with the larger numerator

• The one with the smaller numerator

What should you do first when practicing making common denominators?

• Add the fractions

• Shade the models

• Multiply the numerators

• Find a common denominator

Which symbol correctly compares two-thirds and nine-twelfths?

• Cannot be compared

• Two-thirds is equal to nine-twelfths

• Two-thirds is less than nine-twelfths

• Two-thirds is greater than nine-twelfths
