How do you solve problems involving division of mixed fractions using appropriate problem solving strategies?

When you divide mixed numbers, there’s a step-by-step process to follow. Let’s walk through it!

For example, let’s say you want to solve:



Step 1: Change the mixed numbers into improper fractions


To change into an improper fraction, look at the image below. First multiply the denominator by the whole number, then add the result to the numerator.

becomes

becomes



Step 2: Flip the second fraction
Now that both numbers are improper fractions, you need to flip the second fraction. So:


Step 3: Multiply the fractions
Instead of dividing, you now multiply the first fraction by the flipped  second fraction. You multiply the numerators and the denominators:


Step 4: Simplify or change back to a mixed number
can't be simplified because there are no common factors. can be written as a mixed number since the numerator is larger than the denominator. 28 divided by 15 is 1 with a remainder of 13. So,
