• Fractions as numbers with specified place-values

• Fractions as directed-numbers (positive and negative)

• Fractions arithmetics : first principles

• fractions arithmetics : simplified procedures

Addition/Subtraction with LCM of denominators

Multiplication by multiplying numerators and denominators

Division as multiplication with multiplicative inverse *(click for the list of lessons in this topic)*

Arithmetics with Fractions

Fractions are specified in different place values or denominators. This page explains arithmetics with fractions such as, comparison, addition, subtraction, multiplication, and division.

The arithmetic operations are first explained in *first-principles* for fractions - numbers with different place-values.

Then *simplified procedures* are explained.
