69 is what percent of 3143 - 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 3143 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 3143, so we can write it down as 100%=3143.
4. We know, that x% equals 69 of the output value, so we can write it down as x%=69.
5. Now we have two simple equations:
1) 100%=3143
2) x%=69
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%=3143/69
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 69 is what percent of 3143

100%/x%=3143/69
(100/x)*x=(3143/69)*x       - we multiply both sides of the equation by x
100=45.550724637681*x       - we divide both sides of the equation by (45.550724637681) to get x
100/45.550724637681=x
2.195354756602=x
x=2.195354756602

now we have:
69 is 2.195354756602% of 3143
