What is 15.6 percent of 251 - 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 251 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 251 is 100%, so we can write it down as 251=100%.
4. We know, that x is 15.6% of the output value, so we can write it down as x=15.6%.
5. Now we have two simple equations:
1) 251=100%
2) x=15.6%
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:
251/x=100%/15.6%
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 15.6% of 251

251/x=100/15.6
(251/x)*x=(100/15.6)*x       - we multiply both sides of the equation by x
251=6.4102564102564*x       - we divide both sides of the equation by (6.4102564102564) to get x
251/6.4102564102564=x
39.156=x
x=39.156

now we have:
15.6% of 251=39.156
