47 is what percent of 36.9 - 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 36.9 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 36.9, so we can write it down as 100%=36.9.
4. We know, that x% equals 47 of the output value, so we can write it down as x%=47.
5. Now we have two simple equations:
1) 100%=36.9
2) x%=47
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%=36.9/47
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 47 is what percent of 36.9

100%/x%=36.9/47
(100/x)*x=(36.9/47)*x       - we multiply both sides of the equation by x
100=0.78510638297872*x       - we divide both sides of the equation by (0.78510638297872) to get x
100/0.78510638297872=x
127.37127371274=x
x=127.37127371274

now we have:
47 is 127.37127371274% of 36.9
