Whats 160% of 19?

show your work

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.

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
