0.64 is what percent of 8.26 - 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 8.26 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 8.26, so we can write it down as 100%=8.26.
4. We know, that x% equals 0.64 of the output value, so we can write it down as x%=0.64.
5. Now we have two simple equations:
1) 100%=8.26
2) x%=0.64
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%=8.26/0.64
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.64 is what percent of 8.26

100%/x%=8.26/0.64
(100/x)*x=(8.26/0.64)*x       - we multiply both sides of the equation by x
100=12.90625*x       - we divide both sides of the equation by (12.90625) to get x
100/12.90625=x
7.7481840193705=x
x=7.7481840193705

now we have:
0.64 is 7.7481840193705% of 8.26
