What is 1.61 percent of 19.8 - 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 19.8 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 19.8 is 100%, so we can write it down as 19.8=100%.
4. We know, that x is 1.61% of the output value, so we can write it down as x=1.61%.
5. Now we have two simple equations:
1) 19.8=100%
2) x=1.61%
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:
19.8/x=100%/1.61%
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 1.61% of 19.8

19.8/x=100/1.61
(19.8/x)*x=(100/1.61)*x       - we multiply both sides of the equation by x
19.8=62.111801242236*x       - we divide both sides of the equation by (62.111801242236) to get x
19.8/62.111801242236=x
0.31878=x
x=0.31878

now we have:
1.61% of 19.8=0.31878
