84.3 is what percent of 287 - 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 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, so we can write it down as 100%=287.
4. We know, that x% equals 84.3 of the output value, so we can write it down as x%=84.3.
5. Now we have two simple equations:
1) 100%=287
2) x%=84.3
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%=287/84.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 84.3 is what percent of 287

100%/x%=287/84.3
(100/x)*x=(287/84.3)*x       - we multiply both sides of the equation by x
100=3.4045077105575*x       - we divide both sides of the equation by (3.4045077105575) to get x
100/3.4045077105575=x
29.372822299652=x
x=29.372822299652

now we have:
84.3 is 29.372822299652% of 287
