348.25 is what percent of 428 - 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 428 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 428, so we can write it down as 100%=428.
4. We know, that x% equals 348.25 of the output value, so we can write it down as x%=348.25.
5. Now we have two simple equations:
1) 100%=428
2) x%=348.25
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%=428/348.25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 348.25 is what percent of 428

100%/x%=428/348.25
(100/x)*x=(428/348.25)*x       - we multiply both sides of the equation by x
100=1.2290021536253*x       - we divide both sides of the equation by (1.2290021536253) to get x
100/1.2290021536253=x
81.366822429907=x
x=81.366822429907

now we have:
348.25 is 81.366822429907% of 428
