What is 2.2 percent of 507 - 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 507 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 507 is 100%, so we can write it down as 507=100%.
4. We know, that x is 2.2% of the output value, so we can write it down as x=2.2%.
5. Now we have two simple equations:
1) 507=100%
2) x=2.2%
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:
507/x=100%/2.2%
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 2.2% of 507

507/x=100/2.2
(507/x)*x=(100/2.2)*x       - we multiply both sides of the equation by x
507=45.454545454545*x       - we divide both sides of the equation by (45.454545454545) to get x
507/45.454545454545=x
11.154=x
x=11.154

now we have:
2.2% of 507=11.154
