43.7 is what percent of 28 - 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 28 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 28, so we can write it down as 100%=28.
4. We know, that x% equals 43.7 of the output value, so we can write it down as x%=43.7.
5. Now we have two simple equations:
1) 100%=28
2) x%=43.7
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%=28/43.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 43.7 is what percent of 28

100%/x%=28/43.7
(100/x)*x=(28/43.7)*x       - we multiply both sides of the equation by x
100=0.64073226544622*x       - we divide both sides of the equation by (0.64073226544622) to get x
100/0.64073226544622=x
156.07142857143=x
x=156.07142857143

now we have:
43.7 is 156.07142857143% of 28
