1. We assume, that the number 19 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 19 is 100%, so we can write it down as 19=100%.
4. We know, that x is 160% of the output value, so we can write it down as x=160%.
5. Now we have two simple equations:
1) 19=100%
2) x=160%
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:
19/x=100%/160%
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 160% of 19
19/x=100/160
(19/x)*x=(100/160)*x - we multiply both sides of the equation by x
19=0.625*x - we divide both sides of the equation by (0.625) to get x
19/0.625=x
30.4=x
x=30.4
now we have:
160% of 19=30.4
