Enter fraction(s) below:

We want to subtract the following 2 fractions:

1
1

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

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
