What is 423 percent of 20.85 - 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 20.85 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 20.85 is 100%, so we can write it down as 20.85=100%.
4. We know, that x is 423% of the output value, so we can write it down as x=423%.
5. Now we have two simple equations:
1) 20.85=100%
2) x=423%
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:
20.85/x=100%/423%
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 423% of 20.85

20.85/x=100/423
(20.85/x)*x=(100/423)*x       - we multiply both sides of the equation by x
20.85=0.23640661938534*x       - we divide both sides of the equation by (0.23640661938534) to get x
20.85/0.23640661938534=x
88.1955=x
x=88.1955

now we have:
423% of 20.85=88.1955
