189.75 is what percent of 12880 - 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 12880 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 12880, so we can write it down as 100%=12880.
4. We know, that x% equals 189.75 of the output value, so we can write it down as x%=189.75.
5. Now we have two simple equations:
1) 100%=12880
2) x%=189.75
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%=12880/189.75
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 189.75 is what percent of 12880

100%/x%=12880/189.75
(100/x)*x=(12880/189.75)*x       - we multiply both sides of the equation by x
100=67.878787878788*x       - we divide both sides of the equation by (67.878787878788) to get x
100/67.878787878788=x
1.4732142857143=x
x=1.4732142857143

now we have:
189.75 is 1.4732142857143% of 12880
