43.19 is what percent of 287.13 - 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 287.13 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 287.13, so we can write it down as 100%=287.13.
4. We know, that x% equals 43.19 of the output value, so we can write it down as x%=43.19.
5. Now we have two simple equations:
1) 100%=287.13
2) x%=43.19
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%=287.13/43.19
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 43.19 is what percent of 287.13

100%/x%=287.13/43.19
(100/x)*x=(287.13/43.19)*x       - we multiply both sides of the equation by x
100=6.6480666821023*x       - we divide both sides of the equation by (6.6480666821023) to get x
100/6.6480666821023=x
15.041967053251=x
x=15.041967053251

now we have:
43.19 is 15.041967053251% of 287.13
