486.45 is what percent of 651 - 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 651 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 651, so we can write it down as 100%=651.
4. We know, that x% equals 486.45 of the output value, so we can write it down as x%=486.45.
5. Now we have two simple equations:
1) 100%=651
2) x%=486.45
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%=651/486.45
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 486.45 is what percent of 651

100%/x%=651/486.45
(100/x)*x=(651/486.45)*x       - we multiply both sides of the equation by x
100=1.3382670366944*x       - we divide both sides of the equation by (1.3382670366944) to get x
100/1.3382670366944=x
74.723502304147=x
x=74.723502304147

now we have:
486.45 is 74.723502304147% of 651
