What is 11.11 percent of 811 - 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 811 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 811 is 100%, so we can write it down as 811=100%.
4. We know, that x is 11.11% of the output value, so we can write it down as x=11.11%.
5. Now we have two simple equations:
1) 811=100%
2) x=11.11%
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:
811/x=100%/11.11%
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 11.11% of 811

811/x=100/11.11
(811/x)*x=(100/11.11)*x       - we multiply both sides of the equation by x
811=9.000900090009*x       - we divide both sides of the equation by (9.000900090009) to get x
811/9.000900090009=x
90.1021=x
x=90.1021

now we have:
11.11% of 811=90.1021
