28 is what percent of 2987 - 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 2987 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 2987, so we can write it down as 100%=2987.
4. We know, that x% equals 28 of the output value, so we can write it down as x%=28.
5. Now we have two simple equations:
1) 100%=2987
2) x%=28
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%=2987/28
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 28 is what percent of 2987

100%/x%=2987/28
(100/x)*x=(2987/28)*x       - we multiply both sides of the equation by x
100=106.67857142857*x       - we divide both sides of the equation by (106.67857142857) to get x
100/106.67857142857=x
0.93739537997991=x
x=0.93739537997991

now we have:
28 is 0.93739537997991% of 2987
