0.64 is what percent of 1.1 - 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 1.1 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 1.1, so we can write it down as 100%=1.1.
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%=1.1
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%=1.1/0.64
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 1.1

100%/x%=1.1/0.64
(100/x)*x=(1.1/0.64)*x       - we multiply both sides of the equation by x
100=1.71875*x       - we divide both sides of the equation by (1.71875) to get x
100/1.71875=x
58.181818181818=x
x=58.181818181818

now we have:
0.64 is 58.181818181818% of 1.1
