What is 1.557 percent of 2.5 - 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 2.5 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 2.5 is 100%, so we can write it down as 2.5=100%.
4. We know, that x is 1.557% of the output value, so we can write it down as x=1.557%.
5. Now we have two simple equations:
1) 2.5=100%
2) x=1.557%
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:
2.5/x=100%/1.557%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 1.557% of 2.5

2.5/x=100/1.557
(2.5/x)*x=(100/1.557)*x       - we multiply both sides of the equation by x
2.5=64.226075786769*x       - we divide both sides of the equation by (64.226075786769) to get x
2.5/64.226075786769=x
0.038925=x
x=0.038925

now we have:
1.557% of 2.5=0.038925
