Enter fraction(s) below:
We want to subtract the following 2 fractions:
| 1 | |
| 1 |
| - |
| 9 |
| 20 |
Match Denominators
Denominator 1 ≠ Denominator 2.
We need matching denominators
Multiply fraction 1 numerator * fraction 2 denominator.
Multiply fraction 2 numerator by the fraction 1 denominator
| Fraction 1 - Fraction 2 = | Numerator 1 * Denominator 2 - Numerator 2 * Denominator 1 |
| Denominator 1 * Denominator 2 |
| Fraction 1 - Fraction 2 = | 1 * 20 - 9 * 1 |
| 1 * 20 |
| Fraction 1 - Fraction 2 = | 20 - 9 |
| 20 |
| Fraction 1 - Fraction 2 = | 11 |
| 20 |
Check if simplified
Our fraction is already reduced.
This means our fraction has a Greatest Common Factor (GCF) = 1.
Therefore, we have our answer:
Answer = 11/20
| Answer = | 11 |
| 20 |
Final Answer
11/20

What 8 formulas are used for the Fractions and Mixed Numbers Calculator?
a/c + b/c = (a + b)/c
a/c - b/c = (a - b)/c
a/c * b/c = ab/c * c
a/b/c/d = ad/bc
Reciprocal of a/b = b/a
a/c - b/c = (a - b)/c
a/c * b/c = ab/c * c
a/b/c/d = ad/bc
Reciprocal of a/b = b/a
What 10 concepts are covered in the Fractions and Mixed Numbers Calculator?
- addition
- math operation involving the sum of elements
- denominator
- The bottom portion of a fraction. For a/b, b is the denominator
- division
- separate a number into parts
- fraction
- how many parts of a certain size exist
a/b where a is the numerator and b is the denominator - mixed number
- a number consisting of an integer and a proper fraction.
- multiplication
- math operation involving the product of elements
- numerator
- the number above the line in a common fraction
- reciprocal
- a number which when multiplied by x yields the multiplicative identity, 1
- simplify
- reducing the expression/fraction/problem in a simpler form.
- subtraction
- math operation involving the difference of elements
