Lesson 4: Multiples

Property

To find the total number of objects in equal groups, skip-count by the number of items in each group.
You say one number for each group.

Examples

Property

A whole number $b$ is a multiple of another whole number $a$ if $b$ can be obtained by skip-counting by $a$, or equivalently, if $b \div a$ results in a whole number (a remainder of 0).
This relationship can be expressed as $b = n \times a$, where $n$ is a non-zero whole number.

Examples

Property

If a number $a$ is a factor of a number $b$, then $b$ is a multiple of $a$.
This inverse relationship can be shown with the equation $b = n \times a$, where $n$ is a whole number.
