47 is what percent of 71 - 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 71 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 71, so we can write it down as 100%=71.
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%=71
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%=71/47
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 71

100%/x%=71/47
(100/x)*x=(71/47)*x       - we multiply both sides of the equation by x
100=1.51063829787*x       - we divide both sides of the equation by (1.51063829787) to get x
100/1.51063829787=x
66.1971830986=x
x=66.1971830986

now we have:
47 is 66.1971830986% of 71
