2.18 is what percent of 64 - 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 64 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 64, so we can write it down as 100%=64.
4. We know, that x% equals 2.18 of the output value, so we can write it down as x%=2.18.
5. Now we have two simple equations:
1) 100%=64
2) x%=2.18
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%=64/2.18
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.18 is what percent of 64

100%/x%=64/2.18
(100/x)*x=(64/2.18)*x       - we multiply both sides of the equation by x
100=29.357798165138*x       - we divide both sides of the equation by (29.357798165138) to get x
100/29.357798165138=x
3.40625=x
x=3.40625

now we have:
2.18 is 3.40625% of 64
