What is 2100 percent of 423 - 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 423 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 423 is 100%, so we can write it down as 423=100%.
4. We know, that x is 2100% of the output value, so we can write it down as x=2100%.
5. Now we have two simple equations:
1) 423=100%
2) x=2100%
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:
423/x=100%/2100%
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 2100% of 423

423/x=100/2100
(423/x)*x=(100/2100)*x       - we multiply both sides of the equation by x
423=0.047619047619048*x       - we divide both sides of the equation by (0.047619047619048) to get x
423/0.047619047619048=x
8883=x
x=8883

now we have:
2100% of 423=8883
