47 is what percent of 389 - 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 389 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 389, so we can write it down as 100%=389.
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%=389
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%=389/47
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 389

100%/x%=389/47
(100/x)*x=(389/47)*x       - we multiply both sides of the equation by x
100=8.2765957446809*x       - we divide both sides of the equation by (8.2765957446809) to get x
100/8.2765957446809=x
12.082262210797=x
x=12.082262210797

now we have:
47 is 12.082262210797% of 389
