What is 172.2 percent of 0.77 - 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 0.77 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 0.77 is 100%, so we can write it down as 0.77=100%.
4. We know, that x is 172.2% of the output value, so we can write it down as x=172.2%.
5. Now we have two simple equations:
1) 0.77=100%
2) x=172.2%
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:
0.77/x=100%/172.2%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 172.2% of 0.77

0.77/x=100/172.2
(0.77/x)*x=(100/172.2)*x       - we multiply both sides of the equation by x
0.77=0.58072009291521*x       - we divide both sides of the equation by (0.58072009291521) to get x
0.77/0.58072009291521=x
1.32594=x
x=1.32594

now we have:
172.2% of 0.77=1.32594
