What is 9.21 percent of 921 - 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 921 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 921 is 100%, so we can write it down as 921=100%.
4. We know, that x is 9.21% of the output value, so we can write it down as x=9.21%.
5. Now we have two simple equations:
1) 921=100%
2) x=9.21%
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:
921/x=100%/9.21%
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 9.21% of 921

921/x=100/9.21
(921/x)*x=(100/9.21)*x       - we multiply both sides of the equation by x
921=10.85776330076*x       - we divide both sides of the equation by (10.85776330076) to get x
921/10.85776330076=x
84.8241=x
x=84.8241

now we have:
9.21% of 921=84.8241
