What is 2.63 percent of 81.5 - 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 81.5 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 81.5 is 100%, so we can write it down as 81.5=100%.
4. We know, that x is 2.63% of the output value, so we can write it down as x=2.63%.
5. Now we have two simple equations:
1) 81.5=100%
2) x=2.63%
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:
81.5/x=100%/2.63%
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 2.63% of 81.5

81.5/x=100/2.63
(81.5/x)*x=(100/2.63)*x       - we multiply both sides of the equation by x
81.5=38.022813688213*x       - we divide both sides of the equation by (38.022813688213) to get x
81.5/38.022813688213=x
2.14345=x
x=2.14345

now we have:
2.63% of 81.5=2.14345
