64 is what percent of 579 - 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 579 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 579, so we can write it down as 100%=579.
4. We know, that x% equals 64 of the output value, so we can write it down as x%=64.
5. Now we have two simple equations:
1) 100%=579
2) x%=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%=579/64
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 64 is what percent of 579

100%/x%=579/64
(100/x)*x=(579/64)*x       - we multiply both sides of the equation by x
100=9.046875*x       - we divide both sides of the equation by (9.046875) to get x
100/9.046875=x
11.053540587219=x
x=11.053540587219

now we have:
64 is 11.053540587219% of 579
