0.63 is what percent of 0.86 - 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 0.86 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 0.86, so we can write it down as 100%=0.86.
4. We know, that x% equals 0.63 of the output value, so we can write it down as x%=0.63.
5. Now we have two simple equations:
1) 100%=0.86
2) x%=0.63
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%=0.86/0.63
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.63 is what percent of 0.86

100%/x%=0.86/0.63
(100/x)*x=(0.86/0.63)*x       - we multiply both sides of the equation by x
100=1.3650793650794*x       - we divide both sides of the equation by (1.3650793650794) to get x
100/1.3650793650794=x
73.255813953488=x
x=73.255813953488

now we have:
0.63 is 73.255813953488% of 0.86
