381 is what percent of 1503 - 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 1503 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 1503, so we can write it down as 100%=1503.
4. We know, that x% equals 381 of the output value, so we can write it down as x%=381.
5. Now we have two simple equations:
1) 100%=1503
2) x%=381
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%=1503/381
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 381 is what percent of 1503

100%/x%=1503/381
(100/x)*x=(1503/381)*x       - we multiply both sides of the equation by x
100=3.9448818897638*x       - we divide both sides of the equation by (3.9448818897638) to get x
100/3.9448818897638=x
25.349301397206=x
x=25.349301397206

now we have:
381 is 25.349301397206% of 1503
