43.6 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 43.6 of the output value, so we can write it down as x%=43.6.
5. Now we have two simple equations:
1) 100%=345
2) x%=43.6
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%=345/43.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 43.6 is what percent of 345

100%/x%=345/43.6
(100/x)*x=(345/43.6)*x       - we multiply both sides of the equation by x
100=7.9128440366972*x       - we divide both sides of the equation by (7.9128440366972) to get x
100/7.9128440366972=x
12.63768115942=x
x=12.63768115942

now we have:
43.6 is 12.63768115942% of 345
