315.5 is what percent of 340 - 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 340 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 340, so we can write it down as 100%=340.
4. We know, that x% equals 315.5 of the output value, so we can write it down as x%=315.5.
5. Now we have two simple equations:
1) 100%=340
2) x%=315.5
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%=340/315.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 315.5 is what percent of 340

100%/x%=340/315.5
(100/x)*x=(340/315.5)*x       - we multiply both sides of the equation by x
100=1.0776545166403*x       - we divide both sides of the equation by (1.0776545166403) to get x
100/1.0776545166403=x
92.794117647059=x
x=92.794117647059

now we have:
315.5 is 92.794117647059% of 340
