Scale Factor of 0.21

Here we will explain what a Scale Factor of 0.21 means and provide you with a Scale Factor of 0.21 Calculator so you calculate either the beginning number (n) or the end number (n prime).

First things first. If you have a "number n" (n), a "number n prime" (n′) and a Scale Factor of 0.21, then it means the following:

n × scale factor = n prime
n × 0.21 = n′

In other words per the equation above, a Scale Factor of 0.21 is the factor that you would multiply with n to get n′.

A scale factor between 0 and 1 will decrease the number and is called a Reduction Scale Factor. A scale factor greater than 1 will increase the number and is called an Enlargement Scale Factor. A scale factor of 1 will not change the number and is called a Congruent Scale Factor.

A Scale Factor of 0.21 is therefore a Reduction Scale Factor.

Below is our useful Scale Factor of 0.21 Calculator where you can either enter n or n′ and we will then calculate the corresponding number.

As we explained above, n prime is calculated by multiplying n by 0.21. This means that when our calculator calculates n, it divides n prime by 0.21. Note also that our answers are rounded to the nearest hundredth if necessary.
