16.45 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 16.45 of the output value, so we can write it down as x%=16.45.
5. Now we have two simple equations:
1) 100%=189
2) x%=16.45
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%=189/16.45
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 16.45 is what percent of 189

100%/x%=189/16.45
(100/x)*x=(189/16.45)*x       - we multiply both sides of the equation by x
100=11.489361702128*x       - we divide both sides of the equation by (11.489361702128) to get x
100/11.489361702128=x
8.7037037037037=x
x=8.7037037037037

now we have:
16.45 is 8.7037037037037% of 189
