How to Add Mixed Fractions?

In order to add mixed fractions, there is a simple process that the calculator uses. Mixed fractions have a whole number and a fraction part:

 

1. Convert the mixed fractions to improper fractions.

 

2. Add the improper fractions together.

 

3. Convert the result back to a mixed fraction if needed.

 

For example, to add 1 1/2 and 2 3/4:

 

- Convert to improper fractions: 3/2 and 11/4.

 

- Find a common denominator and add: 3/2 = 6/4, so 6/4 + 11/4 = 17/4.

 

- Convert back to a mixed fraction: 17/4 = 4 1/4.

Common Mistakes and How to Avoid Them When Using the Adding Mixed Fractions Calculator

We may think that when using a calculator, mistakes will not happen. But it is possible for children to make mistakes when using a calculator.

Mistake 1

Red Cross Icon Indicating Mistakes to Avoid in This Math Topic

Not converting mixed fractions to improper fractions before addition.

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

Ensure that you convert mixed fractions to improper fractions before adding. This is crucial for accurate results.

Mistake 2

Red Cross Icon Indicating Mistakes to Avoid in This Math Topic

Incorrect simplification of fractions.

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

After obtaining the result, ensure you simplify the fraction correctly. For example, 6/8 should be simplified to 3/4.

Mistake 3

Red Cross Icon Indicating Mistakes to Avoid in This Math Topic

Forgetting to convert the final improper fraction back to a mixed fraction.

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

Once the sum is obtained, convert it back to a mixed fraction if necessary. Improper fractions are not the final result for mixed fractions.

Mistake 4

Red Cross Icon Indicating Mistakes to Avoid in This Math Topic

Relying solely on the calculator without understanding the process.

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

Understand the steps involved in adding mixed fractions. This helps in verifying the calculator output.

Mistake 5

Red Cross Icon Indicating Mistakes to Avoid in This Math Topic

Assuming all calculators will handle all fractions correctly.

Problem 1

How would you add 1 1/3 and 2 2/5?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Convert to improper fractions: 1 1/3 = 4/3 and 2 2/5 = 12/5.

 

Find a common denominator: 4/3 = 20/15 and 12/5 = 36/15.

 

Add them: 20/15 + 36/15 = 56/15.

 

Convert to a mixed fraction: 56/15 = 3 11/15.

Explanation

By converting to improper fractions and finding a common denominator, we add and convert back to a mixed fraction.

Problem 3

A recipe requires adding 5 2/3 and 2 3/5. How would you calculate this?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Convert to improper fractions: 5 2/3 = 17/3 and 2 3/5 = 13/5.

 

Find a common denominator: 17/3 = 85/15 and 13/5 = 39/15.

 

Add them: 85/15 + 39/15 = 124/15.

 

Convert to a mixed fraction: 124/15 = 8 4/15.

Explanation

The process involves converting to improper fractions, adding, and converting back to mixed fractions.
