278.13 is what percent of 3000 - 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 3000 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 100% equals 3000, so we can write it down as 100%=3000.
4. We know, that x% equals 278.13 of the output value, so we can write it down as x%=278.13.
5. Now we have two simple equations:
1) 100%=3000
2) x%=278.13
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:
100%/x%=3000/278.13
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 278.13 is what percent of 3000

100%/x%=3000/278.13
(100/x)*x=(3000/278.13)*x       - we multiply both sides of the equation by x
100=10.786322942509*x       - we divide both sides of the equation by (10.786322942509) to get x
100/10.786322942509=x
9.271=x
x=9.271

now we have:
278.13 is 9.271% of 3000
