19.5 is what percent of 573 - 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 573 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 100% equals 573, so we can write it down as 100%=573.
4. We know, that x% equals 19.5 of the output value, so we can write it down as x%=19.5.
5. Now we have two simple equations:
1) 100%=573
2) x%=19.5
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:
100%/x%=573/19.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 19.5 is what percent of 573

100%/x%=573/19.5
(100/x)*x=(573/19.5)*x       - we multiply both sides of the equation by x
100=29.384615384615*x       - we divide both sides of the equation by (29.384615384615) to get x
100/29.384615384615=x
3.4031413612565=x
x=3.4031413612565

now we have:
19.5 is 3.4031413612565% of 573
