28.43 is what percent of 845 - 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 845 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 845, so we can write it down as 100%=845.
4. We know, that x% equals 28.43 of the output value, so we can write it down as x%=28.43.
5. Now we have two simple equations:
1) 100%=845
2) x%=28.43
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%=845/28.43
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 28.43 is what percent of 845

100%/x%=845/28.43
(100/x)*x=(845/28.43)*x       - we multiply both sides of the equation by x
100=29.722124516356*x       - we divide both sides of the equation by (29.722124516356) to get x
100/29.722124516356=x
3.3644970414201=x
x=3.3644970414201

now we have:
28.43 is 3.3644970414201% of 845
