What is 21750 percent of 30 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 30 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 30 is 100%, so we can write it down as 30=100%.
4. We know, that x is 21750% of the output value, so we can write it down as x=21750%.
5. Now we have two simple equations:
1) 30=100%
2) x=21750%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
30/x=100%/21750%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 21750% of 30

30/x=100/21750
(30/x)*x=(100/21750)*x       - we multiply both sides of the equation by x
30=0.0045977011494253*x       - we divide both sides of the equation by (0.0045977011494253) to get x
30/0.0045977011494253=x
6525=x
x=6525

now we have:
21750% of 30=6525
