What is 94.5 percent of 19 - 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 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 is 100%, so we can write it down as 19=100%.
4. We know, that x is 94.5% of the output value, so we can write it down as x=94.5%.
5. Now we have two simple equations:
1) 19=100%
2) x=94.5%
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:
19/x=100%/94.5%
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 94.5% of 19

19/x=100/94.5
(19/x)*x=(100/94.5)*x       - we multiply both sides of the equation by x
19=1.0582010582011*x       - we divide both sides of the equation by (1.0582010582011) to get x
19/1.0582010582011=x
17.955=x
x=17.955

now we have:
94.5% of 19=17.955
