57 is what percent of 1510 - 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 1510 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 1510, so we can write it down as 100%=1510.
4. We know, that x% equals 57 of the output value, so we can write it down as x%=57.
5. Now we have two simple equations:
1) 100%=1510
2) x%=57
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%=1510/57
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 57 is what percent of 1510

100%/x%=1510/57
(100/x)*x=(1510/57)*x       - we multiply both sides of the equation by x
100=26.491228070175*x       - we divide both sides of the equation by (26.491228070175) to get x
100/26.491228070175=x
3.7748344370861=x
x=3.7748344370861

now we have:
57 is 3.7748344370861% of 1510
