8 is what percent of 712 - 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 712 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 712, so we can write it down as 100%=712.
4. We know, that x% equals 8 of the output value, so we can write it down as x%=8.
5. Now we have two simple equations:
1) 100%=712
2) x%=8
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%=712/8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8 is what percent of 712

100%/x%=712/8
(100/x)*x=(712/8)*x       - we multiply both sides of the equation by x
100=89*x       - we divide both sides of the equation by (89) to get x
100/89=x
1.123595505618=x
x=1.123595505618

now we have:
8 is 1.123595505618% of 712
