102.9 is what percent of 210000 - 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 210000 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 210000, so we can write it down as 100%=210000.
4. We know, that x% equals 102.9 of the output value, so we can write it down as x%=102.9.
5. Now we have two simple equations:
1) 100%=210000
2) x%=102.9
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%=210000/102.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 102.9 is what percent of 210000

100%/x%=210000/102.9
(100/x)*x=(210000/102.9)*x       - we multiply both sides of the equation by x
100=2040.8163265306*x       - we divide both sides of the equation by (2040.8163265306) to get x
100/2040.8163265306=x
0.049=x
x=0.049

now we have:
102.9 is 0.049% of 210000
