345.5 is what percent of 1080 - 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 1080 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 1080, so we can write it down as 100%=1080.
4. We know, that x% equals 345.5 of the output value, so we can write it down as x%=345.5.
5. Now we have two simple equations:
1) 100%=1080
2) x%=345.5
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%=1080/345.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 345.5 is what percent of 1080

100%/x%=1080/345.5
(100/x)*x=(1080/345.5)*x       - we multiply both sides of the equation by x
100=3.1259044862518*x       - we divide both sides of the equation by (3.1259044862518) to get x
100/3.1259044862518=x
31.990740740741=x
x=31.990740740741

now we have:
345.5 is 31.990740740741% of 1080
