Reciprocal

Reciprocal = What to multiply a value by to get 1 (how to get ONE).

A reciprocal is 1 divided by that number

At the log cutting competition, one person used a Reciprocating (reciprocal) saw and WON (1).

Example 1

What is the reciprocal of $5$ ?

The reciprocal of $5$ is worked out by putting a one under the $5$ and turning it into a fraction and then turning the fraction upside down.

$5 rArr5/1$ turn over $1/5$

So the reciprocal of $5$ is $1/5$ (or $0.2$ )

(To check multiply $0.2times5$ and you get $1$ )

Example 2

What is the reciprocal of $8$ .

The reciprocal of $8$ is worked out by putting a one under the $8$ and turning it into a fraction and then turning the fraction upside down.

$8rArr8/1$ turn over $1/8$

So the reciprocal of $8$ is $1/8$ (or $0.125$ )

(To check multiply $0.125times8$ and you get $1$ )

Example 3

What is the reciprocal of $1000$ .

The reciprocal of $1000$ is worked out by putting a one under the $1000$ and turning it to a fraction and then turning the fraction upside down.

$1000rArr1000/1$ turn over $1/1000$

So the reciprocal of $1000$ is $1/1000$ (or $0.001$ )

(To check multiply $0.001times1000$ and you get $1$ )

Example 4

What is the reciprocal of $3/4$

The reciprocal of $3/4$ is worked out by putting a one under the $3/4$ and turning it into a fraction and then turning the fraction upside down.

$3/4rArr3/(4times1)$ turn over $(1times4)/3$

So the reciprocal of $3/4$ is $4/3$

(To check multiply $3/4times4/3$ and you get $1$ )
