476.5 is what percent of 690 - 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 690 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 690, so we can write it down as 100%=690.
4. We know, that x% equals 476.5 of the output value, so we can write it down as x%=476.5.
5. Now we have two simple equations:
1) 100%=690
2) x%=476.5
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%=690/476.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 476.5 is what percent of 690

100%/x%=690/476.5
(100/x)*x=(690/476.5)*x       - we multiply both sides of the equation by x
100=1.4480587618048*x       - we divide both sides of the equation by (1.4480587618048) to get x
100/1.4480587618048=x
69.057971014493=x
x=69.057971014493

now we have:
476.5 is 69.057971014493% of 690
