768 is what percent of 1071 - 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 1071 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 1071, so we can write it down as 100%=1071.
4. We know, that x% equals 768 of the output value, so we can write it down as x%=768.
5. Now we have two simple equations:
1) 100%=1071
2) x%=768
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%=1071/768
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 768 is what percent of 1071

100%/x%=1071/768
(100/x)*x=(1071/768)*x       - we multiply both sides of the equation by x
100=1.39453125*x       - we divide both sides of the equation by (1.39453125) to get x
100/1.39453125=x
71.708683473389=x
x=71.708683473389

now we have:
768 is 71.708683473389% of 1071
