0.77 is what percent of 5 - 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 5 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 5, so we can write it down as 100%=5.
4. We know, that x% equals 0.77 of the output value, so we can write it down as x%=0.77.
5. Now we have two simple equations:
1) 100%=5
2) x%=0.77
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%=5/0.77
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.77 is what percent of 5

100%/x%=5/0.77
(100/x)*x=(5/0.77)*x       - we multiply both sides of the equation by x
100=6.4935064935065*x       - we divide both sides of the equation by (6.4935064935065) to get x
100/6.4935064935065=x
15.4=x
x=15.4

now we have:
0.77 is 15.4% of 5
