670.21 is what percent of 720 - 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 720 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 720, so we can write it down as 100%=720.
4. We know, that x% equals 670.21 of the output value, so we can write it down as x%=670.21.
5. Now we have two simple equations:
1) 100%=720
2) x%=670.21
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%=720/670.21
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 670.21 is what percent of 720

100%/x%=720/670.21
(100/x)*x=(720/670.21)*x       - we multiply both sides of the equation by x
100=1.0742901478641*x       - we divide both sides of the equation by (1.0742901478641) to get x
100/1.0742901478641=x
93.084722222222=x
x=93.084722222222

now we have:
670.21 is 93.084722222222% of 720
