64 is what percent of 5.1 - 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 5.1 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 5.1, so we can write it down as 100%=5.1.
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%=5.1
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%=5.1/64
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 5.1

100%/x%=5.1/64
(100/x)*x=(5.1/64)*x       - we multiply both sides of the equation by x
100=0.0796875*x       - we divide both sides of the equation by (0.0796875) to get x
100/0.0796875=x
1254.9019607843=x
x=1254.9019607843

now we have:
64 is 1254.9019607843% of 5.1
