288.5 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 288.5 of the output value, so we can write it down as x%=288.5.
5. Now we have two simple equations:
1) 100%=340
2) x%=288.5
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%=340/288.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 288.5 is what percent of 340

100%/x%=340/288.5
(100/x)*x=(340/288.5)*x       - we multiply both sides of the equation by x
100=1.1785095320624*x       - we divide both sides of the equation by (1.1785095320624) to get x
100/1.1785095320624=x
84.852941176471=x
x=84.852941176471

now we have:
288.5 is 84.852941176471% of 340
