231.75 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 231.75 of the output value, so we can write it down as x%=231.75.
5. Now we have two simple equations:
1) 100%=345
2) x%=231.75
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%=345/231.75
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 231.75 is what percent of 345

100%/x%=345/231.75
(100/x)*x=(345/231.75)*x       - we multiply both sides of the equation by x
100=1.4886731391586*x       - we divide both sides of the equation by (1.4886731391586) to get x
100/1.4886731391586=x
67.173913043478=x
x=67.173913043478

now we have:
231.75 is 67.173913043478% of 345
