This video tutorial explains how to change the form of fractions without altering their value. It covers the concepts of proper and improper fractions, and how to convert between improper fractions and mixed numbers. The tutorial also discusses the advantages of using improper fractions in arithmetic operations and provides examples of conversions using the number line.

What is a proper fraction?

• A fraction with a numerator smaller than the denominator

• A fraction with a numerator larger than the denominator

• A fraction equal to one

• A fraction with a negative numerator

How can you identify an improper fraction?

• The numerator is less than the denominator

• The numerator is greater than or equal to the denominator

• The fraction is negative

What is a mixed number?

• A fraction with a whole number and a proper fraction

• A fraction equal to zero

• A fraction with a numerator larger than the denominator

• A fraction with a numerator smaller than the denominator

How do you convert an improper fraction to a mixed number?
