What is 1.6 percent of 19900 - 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 19900 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 19900 is 100%, so we can write it down as 19900=100%.
4. We know, that x is 1.6% of the output value, so we can write it down as x=1.6%.
5. Now we have two simple equations:
1) 19900=100%
2) x=1.6%
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:
19900/x=100%/1.6%
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 1.6% of 19900

19900/x=100/1.6
(19900/x)*x=(100/1.6)*x       - we multiply both sides of the equation by x
19900=62.5*x       - we divide both sides of the equation by (62.5) to get x
19900/62.5=x
318.4=x
x=318.4

now we have:
1.6% of 19900=318.4
