155.99 is what percent of 189 - 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 189 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 189, so we can write it down as 100%=189.
4. We know, that x% equals 155.99 of the output value, so we can write it down as x%=155.99.
5. Now we have two simple equations:
1) 100%=189
2) x%=155.99
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%=189/155.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 155.99 is what percent of 189

100%/x%=189/155.99
(100/x)*x=(189/155.99)*x       - we multiply both sides of the equation by x
100=1.2116161292391*x       - we divide both sides of the equation by (1.2116161292391) to get x
100/1.2116161292391=x
82.534391534392=x
x=82.534391534392

now we have:
155.99 is 82.534391534392% of 189
