449.16 is what percent of 2100 - 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 2100 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 100% equals 2100, so we can write it down as 100%=2100.
4. We know, that x% equals 449.16 of the output value, so we can write it down as x%=449.16.
5. Now we have two simple equations:
1) 100%=2100
2) x%=449.16
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:
100%/x%=2100/449.16
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 449.16 is what percent of 2100

100%/x%=2100/449.16
(100/x)*x=(2100/449.16)*x       - we multiply both sides of the equation by x
100=4.6753940689287*x       - we divide both sides of the equation by (4.6753940689287) to get x
100/4.6753940689287=x
21.388571428571=x
x=21.388571428571

now we have:
449.16 is 21.388571428571% of 2100
