51 is what percent of 721000 - 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 721000 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 721000, so we can write it down as 100%=721000.
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%=721000
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%=721000/51
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 721000

100%/x%=721000/51
(100/x)*x=(721000/51)*x       - we multiply both sides of the equation by x
100=14137.254901961*x       - we divide both sides of the equation by (14137.254901961) to get x
100/14137.254901961=x
0.0070735090152566=x
x=0.0070735090152566

now we have:
51 is 0.0070735090152566% of 721000
