643.37 is what percent of 760 - 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 760 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 760, so we can write it down as 100%=760.
4. We know, that x% equals 643.37 of the output value, so we can write it down as x%=643.37.
5. Now we have two simple equations:
1) 100%=760
2) x%=643.37
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%=760/643.37
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 643.37 is what percent of 760

100%/x%=760/643.37
(100/x)*x=(760/643.37)*x       - we multiply both sides of the equation by x
100=1.1812798234298*x       - we divide both sides of the equation by (1.1812798234298) to get x
100/1.1812798234298=x
84.653947368421=x
x=84.653947368421

now we have:
643.37 is 84.653947368421% of 760
