Fraction can be expressed in two different forms: display notation and in-line notation , where a is the numerator, and b is the denominator.
The numerator shows how many of parts belong to the fraction and the denominator shows into what parts the unit is divided.
Here are some basic formulas with fractions:
Addition: a/b + c/d = ad/bd + bc/bd = (ad + bc)/bd
Subtraction: a/b - c/d = ad/bd - bc/bd = (ad - bc)/bd
Multiplication: a/b · c/d = ac/bd
Division: (a/b)/(c/d) = ad/bc
Here is the fraction calculator that will help you to compute fractions.
