What is 8.9 percent of 31500 - 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 31500 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 31500 is 100%, so we can write it down as 31500=100%.
4. We know, that x is 8.9% of the output value, so we can write it down as x=8.9%.
5. Now we have two simple equations:
1) 31500=100%
2) x=8.9%
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:
31500/x=100%/8.9%
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 8.9% of 31500

31500/x=100/8.9
(31500/x)*x=(100/8.9)*x       - we multiply both sides of the equation by x
31500=11.23595505618*x       - we divide both sides of the equation by (11.23595505618) to get x
31500/11.23595505618=x
2803.5=x
x=2803.5

now we have:
8.9% of 31500=2803.5
