Dividing Mixed Numbers and Fractions

The video tutorial explains how to divide mixed numbers by fractions using two methods. The first method involves converting mixed numbers into improper fractions and using the 'keep change flip' technique. The second method involves simplifying complex fractions by converting mixed numbers into whole numbers and fractions. The tutorial provides three examples to illustrate these methods, demonstrating the conversion process, multiplication, and simplification steps. The video concludes with a summary of the methods and encourages viewers to explore additional resources for further learning.

What is the first step in dividing a mixed number by a fraction using the first method?

• Multiply the mixed number by the fraction

• Convert the mixed number to an improper fraction

• Add the mixed number to the fraction

• Convert the mixed number to a decimal

In the first example, what is the improper fraction form of 8 and 2/5?

• 42/5

• 40/5

• 45/5

• 38/5
