65 is what percent of 4120 - 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 4120 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 4120, so we can write it down as 100%=4120.
4. We know, that x% equals 65 of the output value, so we can write it down as x%=65.
5. Now we have two simple equations:
1) 100%=4120
2) x%=65
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%=4120/65
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 65 is what percent of 4120

100%/x%=4120/65
(100/x)*x=(4120/65)*x       - we multiply both sides of the equation by x
100=63.384615384615*x       - we divide both sides of the equation by (63.384615384615) to get x
100/63.384615384615=x
1.5776699029126=x
x=1.5776699029126

now we have:
65 is 1.5776699029126% of 4120
