643.72 is what percent of 484 - 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 484 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 484, so we can write it down as 100%=484.
4. We know, that x% equals 643.72 of the output value, so we can write it down as x%=643.72.
5. Now we have two simple equations:
1) 100%=484
2) x%=643.72
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%=484/643.72
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 643.72 is what percent of 484

100%/x%=484/643.72
(100/x)*x=(484/643.72)*x       - we multiply both sides of the equation by x
100=0.75187969924812*x       - we divide both sides of the equation by (0.75187969924812) to get x
100/0.75187969924812=x
133=x
x=133

now we have:
643.72 is 133% of 484
