280 is what percent of 3 - 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 3 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 3, so we can write it down as 100%=3.
4. We know, that x% equals 280 of the output value, so we can write it down as x%=280.
5. Now we have two simple equations:
1) 100%=3
2) x%=280
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%=3/280
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 280 is what percent of 3

100%/x%=3/280
(100/x)*x=(3/280)*x       - we multiply both sides of the equation by x
100=0.0107142857143*x       - we divide both sides of the equation by (0.0107142857143) to get x
100/0.0107142857143=x
9333.33333333=x
x=9333.33333333

now we have:
280 is 9333.33333333% of 3
