227.5 is what percent of 2990 - 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 2990 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 2990, so we can write it down as 100%=2990.
4. We know, that x% equals 227.5 of the output value, so we can write it down as x%=227.5.
5. Now we have two simple equations:
1) 100%=2990
2) x%=227.5
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%=2990/227.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 227.5 is what percent of 2990

100%/x%=2990/227.5
(100/x)*x=(2990/227.5)*x       - we multiply both sides of the equation by x
100=13.142857142857*x       - we divide both sides of the equation by (13.142857142857) to get x
100/13.142857142857=x
7.6086956521739=x
x=7.6086956521739

now we have:
227.5 is 7.6086956521739% of 2990
