Fractions high level — Foundational Concepts & Equivalence + 6 more topics

Fractions are all about sharing or dividing a whole into equal parts. You'll always see two numbers separated by a line:

$$\frac{\text{Numerator}}{\text{Denominator}}$$

• The numerator (top number) tells you how many parts you have or are considering.
• The denominator (bottom number) tells you how many equal parts the whole is divided into. It cannot be zero because you can't divide something into zero parts.
