291.84 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 291.84 of the output value, so we can write it down as x%=291.84.
5. Now we have two simple equations:
1) 100%=345
2) x%=291.84
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%=345/291.84
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 291.84 is what percent of 345

100%/x%=345/291.84
(100/x)*x=(345/291.84)*x       - we multiply both sides of the equation by x
100=1.1821546052632*x       - we divide both sides of the equation by (1.1821546052632) to get x
100/1.1821546052632=x
84.591304347826=x
x=84.591304347826

now we have:
291.84 is 84.591304347826% of 345
