What is 10000 percent of 19.9 - 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 19.9 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 19.9 is 100%, so we can write it down as 19.9=100%.
4. We know, that x is 10000% of the output value, so we can write it down as x=10000%.
5. Now we have two simple equations:
1) 19.9=100%
2) x=10000%
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:
19.9/x=100%/10000%
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 10000% of 19.9

19.9/x=100/10000
(19.9/x)*x=(100/10000)*x       - we multiply both sides of the equation by x
19.9=0.01*x       - we divide both sides of the equation by (0.01) to get x
19.9/0.01=x
1990=x
x=1990

now we have:
10000% of 19.9=1990
