denominator

• Common fractions that you can judge other numbers against
• A whole number that is a common multiple of all the denominators of a set of fractions.
• the "bottom" number in a fraction that shows how many equal parts the item is divided into; the divisor of a fraction
• any part of a group, number or whole
