What is 15.7 percent of 189.99 - 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 189.99 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 189.99 is 100%, so we can write it down as 189.99=100%.
4. We know, that x is 15.7% of the output value, so we can write it down as x=15.7%.
5. Now we have two simple equations:
1) 189.99=100%
2) x=15.7%
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:
189.99/x=100%/15.7%
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 15.7% of 189.99

189.99/x=100/15.7
(189.99/x)*x=(100/15.7)*x       - we multiply both sides of the equation by x
189.99=6.3694267515924*x       - we divide both sides of the equation by (6.3694267515924) to get x
189.99/6.3694267515924=x
29.82843=x
x=29.82843

now we have:
15.7% of 189.99=29.82843
