646.5 is what percent of 848 - 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 848 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 848, so we can write it down as 100%=848.
4. We know, that x% equals 646.5 of the output value, so we can write it down as x%=646.5.
5. Now we have two simple equations:
1) 100%=848
2) x%=646.5
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%=848/646.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 646.5 is what percent of 848

100%/x%=848/646.5
(100/x)*x=(848/646.5)*x       - we multiply both sides of the equation by x
100=1.3116782675947*x       - we divide both sides of the equation by (1.3116782675947) to get x
100/1.3116782675947=x
76.23820754717=x
x=76.23820754717

now we have:
646.5 is 76.23820754717% of 848
