64.8 is what percent of 1565.4 - 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 1565.4 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 1565.4, so we can write it down as 100%=1565.4.
4. We know, that x% equals 64.8 of the output value, so we can write it down as x%=64.8.
5. Now we have two simple equations:
1) 100%=1565.4
2) x%=64.8
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%=1565.4/64.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 64.8 is what percent of 1565.4

100%/x%=1565.4/64.8
(100/x)*x=(1565.4/64.8)*x       - we multiply both sides of the equation by x
100=24.157407407407*x       - we divide both sides of the equation by (24.157407407407) to get x
100/24.157407407407=x
4.1395170563434=x
x=4.1395170563434

now we have:
64.8 is 4.1395170563434% of 1565.4
