756 is what percent of 3456 - 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 3456 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 3456, so we can write it down as 100%=3456.
4. We know, that x% equals 756 of the output value, so we can write it down as x%=756.
5. Now we have two simple equations:
1) 100%=3456
2) x%=756
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%=3456/756
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 756 is what percent of 3456

100%/x%=3456/756
(100/x)*x=(3456/756)*x       - we multiply both sides of the equation by x
100=4.5714285714286*x       - we divide both sides of the equation by (4.5714285714286) to get x
100/4.5714285714286=x
21.875=x
x=21.875

now we have:
756 is 21.875% of 3456
