47 is what percent of 2040 - 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 2040 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 2040, so we can write it down as 100%=2040.
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%=2040
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%=2040/47
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 2040

100%/x%=2040/47
(100/x)*x=(2040/47)*x       - we multiply both sides of the equation by x
100=43.404255319149*x       - we divide both sides of the equation by (43.404255319149) to get x
100/43.404255319149=x
2.3039215686275=x
x=2.3039215686275

now we have:
47 is 2.3039215686275% of 2040
