What is 2.123 percent of 458 - 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 458 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 458 is 100%, so we can write it down as 458=100%.
4. We know, that x is 2.123% of the output value, so we can write it down as x=2.123%.
5. Now we have two simple equations:
1) 458=100%
2) x=2.123%
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:
458/x=100%/2.123%
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 2.123% of 458

458/x=100/2.123
(458/x)*x=(100/2.123)*x       - we multiply both sides of the equation by x
458=47.103155911446*x       - we divide both sides of the equation by (47.103155911446) to get x
458/47.103155911446=x
9.72334=x
x=9.72334

now we have:
2.123% of 458=9.72334
