24.15 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 24.15 of the output value, so we can write it down as x%=24.15.
5. Now we have two simple equations:
1) 100%=345
2) x%=24.15
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%=345/24.15
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 24.15 is what percent of 345

100%/x%=345/24.15
(100/x)*x=(345/24.15)*x       - we multiply both sides of the equation by x
100=14.285714285714*x       - we divide both sides of the equation by (14.285714285714) to get x
100/14.285714285714=x
7=x
x=7

now we have:
24.15 is 7% of 345
