What is 77.25 percent of 172 - 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 172 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 172 is 100%, so we can write it down as 172=100%.
4. We know, that x is 77.25% of the output value, so we can write it down as x=77.25%.
5. Now we have two simple equations:
1) 172=100%
2) x=77.25%
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:
172/x=100%/77.25%
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 77.25% of 172

172/x=100/77.25
(172/x)*x=(100/77.25)*x       - we multiply both sides of the equation by x
172=1.294498381877*x       - we divide both sides of the equation by (1.294498381877) to get x
172/1.294498381877=x
132.87=x
x=132.87

now we have:
77.25% of 172=132.87
