What is 2.89 percent of 305 - 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 305 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 305 is 100%, so we can write it down as 305=100%.
4. We know, that x is 2.89% of the output value, so we can write it down as x=2.89%.
5. Now we have two simple equations:
1) 305=100%
2) x=2.89%
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:
305/x=100%/2.89%
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 2.89% of 305

305/x=100/2.89
(305/x)*x=(100/2.89)*x       - we multiply both sides of the equation by x
305=34.602076124567*x       - we divide both sides of the equation by (34.602076124567) to get x
305/34.602076124567=x
8.8145=x
x=8.8145

now we have:
2.89% of 305=8.8145
