51 is what percent of 537 - 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 537 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 537, so we can write it down as 100%=537.
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%=537
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%=537/51
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 537

100%/x%=537/51
(100/x)*x=(537/51)*x       - we multiply both sides of the equation by x
100=10.529411764706*x       - we divide both sides of the equation by (10.529411764706) to get x
100/10.529411764706=x
9.4972067039106=x
x=9.4972067039106

now we have:
51 is 9.4972067039106% of 537
