301.25 is what percent of 345 - 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 345 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 345, so we can write it down as 100%=345.
4. We know, that x% equals 301.25 of the output value, so we can write it down as x%=301.25.
5. Now we have two simple equations:
1) 100%=345
2) x%=301.25
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%=345/301.25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 301.25 is what percent of 345

100%/x%=345/301.25
(100/x)*x=(345/301.25)*x       - we multiply both sides of the equation by x
100=1.1452282157676*x       - we divide both sides of the equation by (1.1452282157676) to get x
100/1.1452282157676=x
87.31884057971=x
x=87.31884057971

now we have:
301.25 is 87.31884057971% of 345
