81.43 is what percent of 328.4 - 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 328.4 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 328.4, so we can write it down as 100%=328.4.
4. We know, that x% equals 81.43 of the output value, so we can write it down as x%=81.43.
5. Now we have two simple equations:
1) 100%=328.4
2) x%=81.43
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%=328.4/81.43
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 81.43 is what percent of 328.4

100%/x%=328.4/81.43
(100/x)*x=(328.4/81.43)*x       - we multiply both sides of the equation by x
100=4.0329117033035*x       - we divide both sides of the equation by (4.0329117033035) to get x
100/4.0329117033035=x
24.795980511571=x
x=24.795980511571

now we have:
81.43 is 24.795980511571% of 328.4
