170.5 is what percent of 873 - 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 873 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 873, so we can write it down as 100%=873.
4. We know, that x% equals 170.5 of the output value, so we can write it down as x%=170.5.
5. Now we have two simple equations:
1) 100%=873
2) x%=170.5
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%=873/170.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 170.5 is what percent of 873

100%/x%=873/170.5
(100/x)*x=(873/170.5)*x       - we multiply both sides of the equation by x
100=5.1202346041056*x       - we divide both sides of the equation by (5.1202346041056) to get x
100/5.1202346041056=x
19.530355097365=x
x=19.530355097365

now we have:
170.5 is 19.530355097365% of 873
