47 is what percent of 1831 - 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 1831 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 1831, so we can write it down as 100%=1831.
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%=1831
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%=1831/47
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 1831

100%/x%=1831/47
(100/x)*x=(1831/47)*x       - we multiply both sides of the equation by x
100=38.957446808511*x       - we divide both sides of the equation by (38.957446808511) to get x
100/38.957446808511=x
2.5669033315128=x
x=2.5669033315128

now we have:
47 is 2.5669033315128% of 1831
