52 is what percent of 4140 - 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 4140 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 4140, so we can write it down as 100%=4140.
4. We know, that x% equals 52 of the output value, so we can write it down as x%=52.
5. Now we have two simple equations:
1) 100%=4140
2) x%=52
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%=4140/52
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 52 is what percent of 4140

100%/x%=4140/52
(100/x)*x=(4140/52)*x       - we multiply both sides of the equation by x
100=79.615384615385*x       - we divide both sides of the equation by (79.615384615385) to get x
100/79.615384615385=x
1.256038647343=x
x=1.256038647343

now we have:
52 is 1.256038647343% of 4140
