5 is what percent of 1247 - 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 1247 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 1247, so we can write it down as 100%=1247.
4. We know, that x% equals 5 of the output value, so we can write it down as x%=5.
5. Now we have two simple equations:
1) 100%=1247
2) x%=5
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%=1247/5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 5 is what percent of 1247

100%/x%=1247/5
(100/x)*x=(1247/5)*x       - we multiply both sides of the equation by x
100=249.4*x       - we divide both sides of the equation by (249.4) to get x
100/249.4=x
0.4009623095429=x
x=0.4009623095429

now we have:
5 is 0.4009623095429% of 1247
