7.7 is what percent of 131.8 - 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 131.8 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 131.8, so we can write it down as 100%=131.8.
4. We know, that x% equals 7.7 of the output value, so we can write it down as x%=7.7.
5. Now we have two simple equations:
1) 100%=131.8
2) x%=7.7
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%=131.8/7.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.7 is what percent of 131.8

100%/x%=131.8/7.7
(100/x)*x=(131.8/7.7)*x       - we multiply both sides of the equation by x
100=17.116883116883*x       - we divide both sides of the equation by (17.116883116883) to get x
100/17.116883116883=x
5.8421851289833=x
x=5.8421851289833

now we have:
7.7 is 5.8421851289833% of 131.8
