What is 1.19 percent of 128.9 - 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 128.9 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 128.9 is 100%, so we can write it down as 128.9=100%.
4. We know, that x is 1.19% of the output value, so we can write it down as x=1.19%.
5. Now we have two simple equations:
1) 128.9=100%
2) x=1.19%
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:
128.9/x=100%/1.19%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 1.19% of 128.9

128.9/x=100/1.19
(128.9/x)*x=(100/1.19)*x       - we multiply both sides of the equation by x
128.9=84.033613445378*x       - we divide both sides of the equation by (84.033613445378) to get x
128.9/84.033613445378=x
1.53391=x
x=1.53391

now we have:
1.19% of 128.9=1.53391
