47 is what percent of 451 - 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 451 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 451, so we can write it down as 100%=451.
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%=451
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%=451/47
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 451

100%/x%=451/47
(100/x)*x=(451/47)*x       - we multiply both sides of the equation by x
100=9.5957446808511*x       - we divide both sides of the equation by (9.5957446808511) to get x
100/9.5957446808511=x
10.421286031042=x
x=10.421286031042

now we have:
47 is 10.421286031042% of 451
