89.68 is what 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 100% equals 172, so we can write it down as 100%=172.
4. We know, that x% equals 89.68 of the output value, so we can write it down as x%=89.68.
5. Now we have two simple equations:
1) 100%=172
2) x%=89.68
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%=172/89.68
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 89.68 is what percent of 172

100%/x%=172/89.68
(100/x)*x=(172/89.68)*x       - we multiply both sides of the equation by x
100=1.9179304192685*x       - we divide both sides of the equation by (1.9179304192685) to get x
100/1.9179304192685=x
52.139534883721=x
x=52.139534883721

now we have:
89.68 is 52.139534883721% of 172
