51 is what percent of 1253 - 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 1253 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 1253, so we can write it down as 100%=1253.
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%=1253
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%=1253/51
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 1253

100%/x%=1253/51
(100/x)*x=(1253/51)*x       - we multiply both sides of the equation by x
100=24.56862745098*x       - we divide both sides of the equation by (24.56862745098) to get x
100/24.56862745098=x
4.0702314445331=x
x=4.0702314445331

now we have:
51 is 4.0702314445331% of 1253
