What is 20000 percent of 8.9 - 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 8.9 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 8.9 is 100%, so we can write it down as 8.9=100%.
4. We know, that x is 20000% of the output value, so we can write it down as x=20000%.
5. Now we have two simple equations:
1) 8.9=100%
2) x=20000%
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:
8.9/x=100%/20000%
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 20000% of 8.9

8.9/x=100/20000
(8.9/x)*x=(100/20000)*x       - we multiply both sides of the equation by x
8.9=0.005*x       - we divide both sides of the equation by (0.005) to get x
8.9/0.005=x
1780=x
x=1780

now we have:
20000% of 8.9=1780
