What is 5.72 percent of 77.2 - 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 77.2 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 77.2 is 100%, so we can write it down as 77.2=100%.
4. We know, that x is 5.72% of the output value, so we can write it down as x=5.72%.
5. Now we have two simple equations:
1) 77.2=100%
2) x=5.72%
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:
77.2/x=100%/5.72%
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 5.72% of 77.2

77.2/x=100/5.72
(77.2/x)*x=(100/5.72)*x       - we multiply both sides of the equation by x
77.2=17.482517482517*x       - we divide both sides of the equation by (17.482517482517) to get x
77.2/17.482517482517=x
4.41584=x
x=4.41584

now we have:
5.72% of 77.2=4.41584
