87 is what percent of 13965 - 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 13965 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 13965, so we can write it down as 100%=13965.
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%=13965
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%=13965/87
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 13965

100%/x%=13965/87
(100/x)*x=(13965/87)*x       - we multiply both sides of the equation by x
100=160.51724137931*x       - we divide both sides of the equation by (160.51724137931) to get x
100/160.51724137931=x
0.62298603651987=x
x=0.62298603651987

now we have:
87 is 0.62298603651987% of 13965
