What is 38.4 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 38.4% of the output value, so we can write it down as x=38.4%.
5. Now we have two simple equations:
1) 305=100%
2) x=38.4%
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%/38.4%
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 38.4% of 305

305/x=100/38.4
(305/x)*x=(100/38.4)*x       - we multiply both sides of the equation by x
305=2.6041666666667*x       - we divide both sides of the equation by (2.6041666666667) to get x
305/2.6041666666667=x
117.12=x
x=117.12

now we have:
38.4% of 305=117.12
