64 is what percent of 1668 - 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 1668 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 1668, so we can write it down as 100%=1668.
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%=1668
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%=1668/64
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 1668

100%/x%=1668/64
(100/x)*x=(1668/64)*x       - we multiply both sides of the equation by x
100=26.0625*x       - we divide both sides of the equation by (26.0625) to get x
100/26.0625=x
3.8369304556355=x
x=3.8369304556355

now we have:
64 is 3.8369304556355% of 1668
