47.5 is what percent of 380 - 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 380 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 380, so we can write it down as 100%=380.
4. We know, that x% equals 47.5 of the output value, so we can write it down as x%=47.5.
5. Now we have two simple equations:
1) 100%=380
2) x%=47.5
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%=380/47.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 47.5 is what percent of 380

100%/x%=380/47.5
(100/x)*x=(380/47.5)*x       - we multiply both sides of the equation by x
100=8*x       - we divide both sides of the equation by (8) to get x
100/8=x
12.5=x
x=12.5

now we have:
47.5 is 12.5% of 380
