4.89 is what percent of 764 - 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 764 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 764, so we can write it down as 100%=764.
4. We know, that x% equals 4.89 of the output value, so we can write it down as x%=4.89.
5. Now we have two simple equations:
1) 100%=764
2) x%=4.89
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%=764/4.89
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4.89 is what percent of 764

100%/x%=764/4.89
(100/x)*x=(764/4.89)*x       - we multiply both sides of the equation by x
100=156.23721881391*x       - we divide both sides of the equation by (156.23721881391) to get x
100/156.23721881391=x
0.64005235602094=x
x=0.64005235602094

now we have:
4.89 is 0.64005235602094% of 764
