# Multiplying Fractions with Unlike Denominators Worksheets

When students see this skill, they are instantly intimidated. This is simple multiplication in a horizontal fashion. You multiply the numerators (top numbers) to form a numerator of the product. You do the same thing with the denominators (bottom numbers). It is all that easy. The only thing to remember is that you will often need to reduce the product that you have created. To do that just find a common multiple that exists between the numerator and the denominator and just pull it out to simplify or reduce the fraction to its lowest value. A collection of worksheets and lessons that shows you how to multiply unlike fractions.

### Aligned Standard: 5.NF.A.1

• Answer Keys - These are for all the unlocked materials above.

### Homework Sheets

Remember to tell the kids to multiply across the pond and then rewrite your product.

• Homework 1 - Multiply the first fraction by the second fraction. It just goes across horizontally.
• Homework 2 - Try flipping the largest numerator first. Keep things spaced out well to go across.
• Homework 3 - This time try it the other way around.

### Practice Worksheets

You have lots of space to work with here. Make sure to use it.

• Practice 1 - Start by multiplying the numerator and then multiply the denominators.
• Practice 2 - I would make these a quick meal for you.
• Practice 3 - Try to power through these problems quickly as possible.

### Math Skill Quizzes

These might be a bit tight for you, but you should use the box area.

• Quiz 1 - Solve all these values. Keep everything clean and well spaced out.
• Quiz 2 - Find the product. We use much larger values now.
• Quiz 3 - See how well you did. Do not get get trapped by using the same numbers.

### How Do You Multiply Fractions with Unlike Denominators?

Out of the four basic arithmetic operations, multiplication, is the trickiest to understand for kids. However, if we look at this operation closely and follow a basic procedure, it is not that difficult. When it comes to applying operations between fractions, multiplication is a much more straightforward operation in comparison to addition, subtraction, and division.

So, there are two cases of multiplication of fractions. The first one is when both fractions have the same denominator (bottom value), and the second case is when the fractions do not have the same denominators. While there is not much difference between the multiplication process in both cases, the unlike denominators can scare the students. Unlike denominators just require an additional step to complete. That step just requires you to find a common denominator between the two fractions within the operation. Use this example to understand how you multiply fractions with unlike denominators.

What you need to do here, multiply the numerator of the first fraction with the numerator of the second one. Do the same with the denominators. Multiply the denominator of the first fraction with that of the second fraction.

If the fraction can be further simplified, you need to reduce it to its simplest form. In this case, there is not a common multiple between 15 and 77, so it cannot be reduced further.
