210.64 is what percent of 240 - 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 240 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 240, so we can write it down as 100%=240.
4. We know, that x% equals 210.64 of the output value, so we can write it down as x%=210.64.
5. Now we have two simple equations:
1) 100%=240
2) x%=210.64
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%=240/210.64
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 210.64 is what percent of 240

100%/x%=240/210.64
(100/x)*x=(240/210.64)*x       - we multiply both sides of the equation by x
100=1.1393847322446*x       - we divide both sides of the equation by (1.1393847322446) to get x
100/1.1393847322446=x
87.766666666667=x
x=87.766666666667

now we have:
210.64 is 87.766666666667% of 240
