500.75 is what percent of 661.75 - 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 661.75 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 661.75, so we can write it down as 100%=661.75.
4. We know, that x% equals 500.75 of the output value, so we can write it down as x%=500.75.
5. Now we have two simple equations:
1) 100%=661.75
2) x%=500.75
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%=661.75/500.75
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 500.75 is what percent of 661.75

100%/x%=661.75/500.75
(100/x)*x=(661.75/500.75)*x       - we multiply both sides of the equation by x
100=1.3215177234149*x       - we divide both sides of the equation by (1.3215177234149) to get x
100/1.3215177234149=x
75.670570457121=x
x=75.670570457121

now we have:
500.75 is 75.670570457121% of 661.75
