52 is what percent of 669 - 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 669 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 669, so we can write it down as 100%=669.
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%=669
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%=669/52
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 669

100%/x%=669/52
(100/x)*x=(669/52)*x       - we multiply both sides of the equation by x
100=12.865384615385*x       - we divide both sides of the equation by (12.865384615385) to get x
100/12.865384615385=x
7.7727952167414=x
x=7.7727952167414

now we have:
52 is 7.7727952167414% of 669
