65.7 is what percent of 356.5 - 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 356.5 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 356.5, so we can write it down as 100%=356.5.
4. We know, that x% equals 65.7 of the output value, so we can write it down as x%=65.7.
5. Now we have two simple equations:
1) 100%=356.5
2) x%=65.7
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%=356.5/65.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 65.7 is what percent of 356.5

100%/x%=356.5/65.7
(100/x)*x=(356.5/65.7)*x       - we multiply both sides of the equation by x
100=5.4261796042618*x       - we divide both sides of the equation by (5.4261796042618) to get x
100/5.4261796042618=x
18.429172510519=x
x=18.429172510519

now we have:
65.7 is 18.429172510519% of 356.5
