Converting Mixed Numbers to Improper Fractions

This video tutorial explains how to convert mixed numbers into improper fractions. It begins by defining mixed numbers and improper fractions, then introduces the 'wheel method' for conversion. The method involves multiplying the whole number by the denominator, adding the numerator, and keeping the denominator unchanged. The video provides three examples: converting 4 and 2/3, 11 and 1/5, and 9 and 3/7 into improper fractions, demonstrating the step-by-step process for each.

What is a mixed number?

• A fraction where the denominator is larger than the numerator

• A fraction that includes a whole number and a fraction

• A fraction that is less than 1

• A fraction where the numerator is larger than the denominator
