The reciprocal of a number is: 1 divided by the number

Examples:

• the reciprocal of 2 is 1/2 (half)

• the reciprocal of 10 is 1/10 (=0.1)

When we multiply a number by its reciprocal we get 1.

Example: 2 × 1/2 = 1

Every number has a reciprocal except 0 (1/0 is undefined)

The reciprocal can be shown with a little "-1" like this: x

Example: 4

Also called the "Multiplicative Inverse"

Examples:

• the reciprocal of 10 is 1/10 (=0.1)

When we multiply a number by its reciprocal we get 1.

Example: 2 × 1/2 = 1

The reciprocal can be shown with a little "-1" like this: x

^{-1}= 1/xExample: 4

^{-1}= 1/4 = 0.25Also called the "Multiplicative Inverse"
