What is 13.3 percent of 278.4 - 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 278.4 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 278.4 is 100%, so we can write it down as 278.4=100%.
4. We know, that x is 13.3% of the output value, so we can write it down as x=13.3%.
5. Now we have two simple equations:
1) 278.4=100%
2) x=13.3%
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:
278.4/x=100%/13.3%
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 13.3% of 278.4

278.4/x=100/13.3
(278.4/x)*x=(100/13.3)*x       - we multiply both sides of the equation by x
278.4=7.5187969924812*x       - we divide both sides of the equation by (7.5187969924812) to get x
278.4/7.5187969924812=x
37.0272=x
x=37.0272

now we have:
13.3% of 278.4=37.0272
