5655 is what percent of 7920 - 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 7920 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 7920, so we can write it down as 100%=7920.
4. We know, that x% equals 5655 of the output value, so we can write it down as x%=5655.
5. Now we have two simple equations:
1) 100%=7920
2) x%=5655
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%=7920/5655
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 5655 is what percent of 7920

100%/x%=7920/5655
(100/x)*x=(7920/5655)*x       - we multiply both sides of the equation by x
100=1.4005305039788*x       - we divide both sides of the equation by (1.4005305039788) to get x
100/1.4005305039788=x
71.401515151515=x
x=71.401515151515

now we have:
5655 is 71.401515151515% of 7920
