64 is what percent of 1276 - 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 1276 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 1276, so we can write it down as 100%=1276.
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%=1276
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%=1276/64
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 1276

100%/x%=1276/64
(100/x)*x=(1276/64)*x       - we multiply both sides of the equation by x
100=19.9375*x       - we divide both sides of the equation by (19.9375) to get x
100/19.9375=x
5.0156739811912=x
x=5.0156739811912

now we have:
64 is 5.0156739811912% of 1276
