What is 2.1022 percent of 121.54 - 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 121.54 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 121.54 is 100%, so we can write it down as 121.54=100%.
4. We know, that x is 2.1022% of the output value, so we can write it down as x=2.1022%.
5. Now we have two simple equations:
1) 121.54=100%
2) x=2.1022%
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:
121.54/x=100%/2.1022%
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 2.1022% of 121.54

121.54/x=100/2.1022
(121.54/x)*x=(100/2.1022)*x       - we multiply both sides of the equation by x
121.54=47.569213205214*x       - we divide both sides of the equation by (47.569213205214) to get x
121.54/47.569213205214=x
2.55501388=x
x=2.55501388

now we have:
2.1022% of 121.54=2.55501388
