What is 3.3 percent of 939 - 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 939 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 939 is 100%, so we can write it down as 939=100%.
4. We know, that x is 3.3% of the output value, so we can write it down as x=3.3%.
5. Now we have two simple equations:
1) 939=100%
2) x=3.3%
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:
939/x=100%/3.3%
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 3.3% of 939

939/x=100/3.3
(939/x)*x=(100/3.3)*x       - we multiply both sides of the equation by x
939=30.30303030303*x       - we divide both sides of the equation by (30.30303030303) to get x
939/30.30303030303=x
30.987=x
x=30.987

now we have:
3.3% of 939=30.987
