What is 21.1 percent of 161 - 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 161 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 161 is 100%, so we can write it down as 161=100%.
4. We know, that x is 21.1% of the output value, so we can write it down as x=21.1%.
5. Now we have two simple equations:
1) 161=100%
2) x=21.1%
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:
161/x=100%/21.1%
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 21.1% of 161

161/x=100/21.1
(161/x)*x=(100/21.1)*x       - we multiply both sides of the equation by x
161=4.739336492891*x       - we divide both sides of the equation by (4.739336492891) to get x
161/4.739336492891=x
33.971=x
x=33.971

now we have:
21.1% of 161=33.971
