What is 150 percent of 12.15 - 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 12.15 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 12.15 is 100%, so we can write it down as 12.15=100%.
4. We know, that x is 150% of the output value, so we can write it down as x=150%.
5. Now we have two simple equations:
1) 12.15=100%
2) x=150%
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:
12.15/x=100%/150%
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 150% of 12.15

12.15/x=100/150
(12.15/x)*x=(100/150)*x       - we multiply both sides of the equation by x
12.15=0.66666666666667*x       - we divide both sides of the equation by (0.66666666666667) to get x
12.15/0.66666666666667=x
18.225=x
x=18.225

now we have:
150% of 12.15=18.225
