12.57 is what percent of 153.94 - 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 153.94 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 153.94, so we can write it down as 100%=153.94.
4. We know, that x% equals 12.57 of the output value, so we can write it down as x%=12.57.
5. Now we have two simple equations:
1) 100%=153.94
2) x%=12.57
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%=153.94/12.57
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 12.57 is what percent of 153.94

100%/x%=153.94/12.57
(100/x)*x=(153.94/12.57)*x       - we multiply both sides of the equation by x
100=12.24661893397*x       - we divide both sides of the equation by (12.24661893397) to get x
100/12.24661893397=x
8.1655190333896=x
x=8.1655190333896

now we have:
12.57 is 8.1655190333896% of 153.94
