What is 87.9 percent of 9.2 - 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 9.2 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 9.2 is 100%, so we can write it down as 9.2=100%.
4. We know, that x is 87.9% of the output value, so we can write it down as x=87.9%.
5. Now we have two simple equations:
1) 9.2=100%
2) x=87.9%
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:
9.2/x=100%/87.9%
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 87.9% of 9.2

9.2/x=100/87.9
(9.2/x)*x=(100/87.9)*x       - we multiply both sides of the equation by x
9.2=1.1376564277588*x       - we divide both sides of the equation by (1.1376564277588) to get x
9.2/1.1376564277588=x
8.0868=x
x=8.0868

now we have:
87.9% of 9.2=8.0868
