173.5 is what percent of 245 - 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 245 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 245, so we can write it down as 100%=245.
4. We know, that x% equals 173.5 of the output value, so we can write it down as x%=173.5.
5. Now we have two simple equations:
1) 100%=245
2) x%=173.5
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%=245/173.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 173.5 is what percent of 245

100%/x%=245/173.5
(100/x)*x=(245/173.5)*x       - we multiply both sides of the equation by x
100=1.4121037463977*x       - we divide both sides of the equation by (1.4121037463977) to get x
100/1.4121037463977=x
70.816326530612=x
x=70.816326530612

now we have:
173.5 is 70.816326530612% of 245
