80 is what percent of 5656 - 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 5656 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 5656, so we can write it down as 100%=5656.
4. We know, that x% equals 80 of the output value, so we can write it down as x%=80.
5. Now we have two simple equations:
1) 100%=5656
2) x%=80
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%=5656/80
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 80 is what percent of 5656

100%/x%=5656/80
(100/x)*x=(5656/80)*x       - we multiply both sides of the equation by x
100=70.7*x       - we divide both sides of the equation by (70.7) to get x
100/70.7=x
1.4144271570014=x
x=1.4144271570014

now we have:
80 is 1.4144271570014% of 5656
