87 is what percent of 1306 - 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 1306 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 1306, so we can write it down as 100%=1306.
4. We know, that x% equals 87 of the output value, so we can write it down as x%=87.
5. Now we have two simple equations:
1) 100%=1306
2) x%=87
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%=1306/87
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 87 is what percent of 1306

100%/x%=1306/87
(100/x)*x=(1306/87)*x       - we multiply both sides of the equation by x
100=15.011494252874*x       - we divide both sides of the equation by (15.011494252874) to get x
100/15.011494252874=x
6.6615620214395=x
x=6.6615620214395

now we have:
87 is 6.6615620214395% of 1306
