How Do You Subtract Fractions?
Fractions With the Same Denominator
When the denominators are the same, subtract the numerators and keep the denominator.
Example:
7/9 − 2/9
Subtract the numerators:
7 − 2 = 5
Therefore:
7/9 − 2/9 = 5/9
Fractions With Different Denominators
When denominators are different, you first need to find a common denominator.
Example:
3/4 − 1/6
The least common denominator is 12.
Convert the fractions:
3/4 = 9/12
1/6 = 2/12
Now subtract:
9/12 − 2/12 = 7/12
Therefore:
3/4 − 1/6 = 7/12
Subtracting Mixed Numbers
A Free Subtract Fractions Calculator may also work with mixed numbers.
Example:
5 1/2 − 2 1/4
Convert to improper fractions:
5 1/2 = 11/2
2 1/4 = 9/4
Convert 11/2 to fourths:
11/2 = 22/4
Then:
22/4 − 9/4 = 13/4
Convert back to a mixed number:
13/4 = 3 1/4
Therefore:
5 1/2 − 2 1/4 = 3 1/4
Why Use a Free Subtract Fractions Calculator?
1. Calculate Fractions Quickly
The calculator performs the subtraction automatically.
2. Handle Different Denominators
It can find a common denominator and convert the fractions for you.
3. Simplify the Result
For example:
12/18 → 2/3
4. Check Homework
Students can verify their manually calculated answers.
5. Learn Fraction Subtraction
Step-by-step calculations can help users understand how common denominators and equivalent fractions work.
Example With Three Fractions
Suppose you need to calculate:
7/8 − 1/4 − 1/8
Convert 1/4 to eighths:
1/4 = 2/8
Then:
7/8 − 2/8 − 1/8 = 4/8
Simplify:
4/8 = 1/2
Therefore:
7/8 − 1/4 − 1/8 = 1/2
Fraction Subtraction and Decimals
Some calculators can also show the decimal equivalent.
For example:
3/4 − 1/6 = 7/12
And:
7/12 ≈ 0.5833
This can be useful when comparing the fraction result with decimal measurements.
