    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

    Well I use whats called the "Fish Method" so it would be set up like this-

    160/100 and?/19. You cross multiply the 19 by the 160, 3040, then divide it by the 100 to get 30.4.
