127.75 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 127.75 of the output value, so we can write it down as x%=127.75.
5. Now we have two simple equations:
1) 100%=170
2) x%=127.75
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%=170/127.75
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 127.75 is what percent of 170

100%/x%=170/127.75
(100/x)*x=(170/127.75)*x       - we multiply both sides of the equation by x
100=1.3307240704501*x       - we divide both sides of the equation by (1.3307240704501) to get x
100/1.3307240704501=x
75.147058823529=x
x=75.147058823529

now we have:
127.75 is 75.147058823529% of 170
