What is 19.89 percent of 155.88 - 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 155.88 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 155.88 is 100%, so we can write it down as 155.88=100%.
4. We know, that x is 19.89% of the output value, so we can write it down as x=19.89%.
5. Now we have two simple equations:
1) 155.88=100%
2) x=19.89%
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:
155.88/x=100%/19.89%
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 19.89% of 155.88

155.88/x=100/19.89
(155.88/x)*x=(100/19.89)*x       - we multiply both sides of the equation by x
155.88=5.0276520864756*x       - we divide both sides of the equation by (5.0276520864756) to get x
155.88/5.0276520864756=x
31.004532=x
x=31.004532

now we have:
19.89% of 155.88=31.004532
