What is 15.25 percent of 121 - 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 121 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 121 is 100%, so we can write it down as 121=100%.
4. We know, that x is 15.25% of the output value, so we can write it down as x=15.25%.
5. Now we have two simple equations:
1) 121=100%
2) x=15.25%
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:
121/x=100%/15.25%
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 15.25% of 121

121/x=100/15.25
(121/x)*x=(100/15.25)*x       - we multiply both sides of the equation by x
121=6.55737704918*x       - we divide both sides of the equation by (6.55737704918) to get x
121/6.55737704918=x
18.4525=x
x=18.4525

now we have:
15.25% of 121=18.4525
