381.5 is what percent of 1030 - 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 1030 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 1030, so we can write it down as 100%=1030.
4. We know, that x% equals 381.5 of the output value, so we can write it down as x%=381.5.
5. Now we have two simple equations:
1) 100%=1030
2) x%=381.5
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%=1030/381.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 381.5 is what percent of 1030

100%/x%=1030/381.5
(100/x)*x=(1030/381.5)*x       - we multiply both sides of the equation by x
100=2.699868938401*x       - we divide both sides of the equation by (2.699868938401) to get x
100/2.699868938401=x
37.038834951456=x
x=37.038834951456

now we have:
381.5 is 37.038834951456% of 1030
