What is 8.875 percent of 990 - 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 990 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 990 is 100%, so we can write it down as 990=100%.
4. We know, that x is 8.875% of the output value, so we can write it down as x=8.875%.
5. Now we have two simple equations:
1) 990=100%
2) x=8.875%
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:
990/x=100%/8.875%
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 8.875% of 990

990/x=100/8.875
(990/x)*x=(100/8.875)*x       - we multiply both sides of the equation by x
990=11.267605633803*x       - we divide both sides of the equation by (11.267605633803) to get x
990/11.267605633803=x
87.8625=x
x=87.8625

now we have:
8.875% of 990=87.8625
