Comparing Fractions by Creating Common Denominators

This video tutorial teaches how to compare fractions by creating common denominators. It explains the components of a fraction, common mistakes in comparing fractions, and the process of finding common denominators using the least common multiple. The tutorial demonstrates converting fractions to have common denominators and compares them by numerators to order them from least to greatest.

What is the main goal when comparing fractions?

• To find the largest numerator

• To create common denominators

• To convert them to decimals

• To add the fractions together

What does the numerator in a fraction represent?

• The value of the fraction

• The number of parts you have

• The number of equal parts in a whole

• The total number of parts in a whole

Why is it incorrect to compare fractions by only looking at the numerators?

• Because the denominators might be the same

• Because the fractions might be improper

• Because the denominators might be different

• Because the numerators might be too large

What is the least common multiple of 3, 2, and 5?

• 30

• 15

• 25

• 20

How do you convert the fraction two-thirds to have a denominator of 30?

• Multiply both numerator and denominator by 10

• Multiply both numerator and denominator by 6

• Multiply both numerator and denominator by 15

• Multiply both numerator and denominator by 5

What is the equivalent fraction of one-half with a denominator of 30?

• 10/30

• 15/30

• 20/30

• 25/30

Which of the following fractions is the largest when converted to a common denominator of 30?

• 15/30

• 20/30

• 24/30
