What is 15.98 percent of 521 - 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 521 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 521 is 100%, so we can write it down as 521=100%.
4. We know, that x is 15.98% of the output value, so we can write it down as x=15.98%.
5. Now we have two simple equations:
1) 521=100%
2) x=15.98%
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:
521/x=100%/15.98%
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 15.98% of 521

521/x=100/15.98
(521/x)*x=(100/15.98)*x       - we multiply both sides of the equation by x
521=6.2578222778473*x       - we divide both sides of the equation by (6.2578222778473) to get x
521/6.2578222778473=x
83.2558=x
x=83.2558

now we have:
15.98% of 521=83.2558
