51 is what percent of 121000 - 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 121000 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 121000, so we can write it down as 100%=121000.
4. We know, that x% equals 51 of the output value, so we can write it down as x%=51.
5. Now we have two simple equations:
1) 100%=121000
2) x%=51
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%=121000/51
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 51 is what percent of 121000

100%/x%=121000/51
(100/x)*x=(121000/51)*x       - we multiply both sides of the equation by x
100=2372.5490196078*x       - we divide both sides of the equation by (2372.5490196078) to get x
100/2372.5490196078=x
0.042148760330579=x
x=0.042148760330579

now we have:
51 is 0.042148760330579% of 121000
