127.49 is what percent of 170 - 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 170 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 170, so we can write it down as 100%=170.
4. We know, that x% equals 127.49 of the output value, so we can write it down as x%=127.49.
5. Now we have two simple equations:
1) 100%=170
2) x%=127.49
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%=170/127.49
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 127.49 is what percent of 170

100%/x%=170/127.49
(100/x)*x=(170/127.49)*x       - we multiply both sides of the equation by x
100=1.3334379166993*x       - we divide both sides of the equation by (1.3334379166993) to get x
100/1.3334379166993=x
74.994117647059=x
x=74.994117647059

now we have:
127.49 is 74.994117647059% of 170
