34 is what percent of 1209 - 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 1209 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 1209, so we can write it down as 100%=1209.
4. We know, that x% equals 34 of the output value, so we can write it down as x%=34.
5. Now we have two simple equations:
1) 100%=1209
2) x%=34
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%=1209/34
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 34 is what percent of 1209

100%/x%=1209/34
(100/x)*x=(1209/34)*x       - we multiply both sides of the equation by x
100=35.558823529412*x       - we divide both sides of the equation by (35.558823529412) to get x
100/35.558823529412=x
2.8122415219189=x
x=2.8122415219189

now we have:
34 is 2.8122415219189% of 1209
