387 is what percent of 5 - 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 5 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 5, so we can write it down as 100%=5.
4. We know, that x% equals 387 of the output value, so we can write it down as x%=387.
5. Now we have two simple equations:
1) 100%=5
2) x%=387
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%=5/387
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 387 is what percent of 5

100%/x%=5/387
(100/x)*x=(5/387)*x       - we multiply both sides of the equation by x
100=0.012919896640827*x       - we divide both sides of the equation by (0.012919896640827) to get x
100/0.012919896640827=x
7740=x
x=7740

now we have:
387 is 7740% of 5
