80 is what percent of 7885 - 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 7885 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 7885, so we can write it down as 100%=7885.
4. We know, that x% equals 80 of the output value, so we can write it down as x%=80.
5. Now we have two simple equations:
1) 100%=7885
2) x%=80
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%=7885/80
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 80 is what percent of 7885

100%/x%=7885/80
(100/x)*x=(7885/80)*x       - we multiply both sides of the equation by x
100=98.5625*x       - we divide both sides of the equation by (98.5625) to get x
100/98.5625=x
1.0145846544071=x
x=1.0145846544071

now we have:
80 is 1.0145846544071% of 7885
