Dividing Mixed Numbers

This lesson teaches how to divide mixed numbers by converting them into improper fractions and using the same change flip method. An example problem is solved by first converting mixed numbers to improper fractions, then applying the method to change division into multiplication by using the reciprocal of the divisor. Cross reduction is performed before multiplying to find the final result. Key points include the necessity of converting mixed numbers and the steps involved in the same change flip method.

What is the first step when dividing mixed numbers?

• Convert them to percentages

• Convert them to whole numbers

• Convert them to decimals

• Convert them to improper fractions

In the example given, what is the improper fraction form of 5 and 1/3?

• 18/3

• 17/3

• 16/3

• 15/3

What is the reciprocal of 14/5?

• 10/7

• 5/14

• 14/5

What is the result of multiplying 8 by 5 in the example?

• 35

• 45

• 50

• 40

Which of the following is a key point from the lesson?

• You can cross reduce before converting to improper fractions

• Cross reduction is not necessary

• You must convert mixed numbers to improper fractions before using the 'same change flip' method

• You should always convert to decimals first
