64 is what percent of 2778 - 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 2778 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 2778, so we can write it down as 100%=2778.
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%=2778
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%=2778/64
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 2778

100%/x%=2778/64
(100/x)*x=(2778/64)*x       - we multiply both sides of the equation by x
100=43.40625*x       - we divide both sides of the equation by (43.40625) to get x
100/43.40625=x
2.3038156947444=x
x=2.3038156947444

now we have:
64 is 2.3038156947444% of 2778
