I believe you would get 0.12 ounces left over.
You bring the numerals on to the other side of the equation, therefore dividing 19 by 3 and 6.
3x + 6y = 19
3x + y = 19/6
x + y = 3.17/3
x + y = 1.1
The answer is 40.4
When you take a percent of the number you make that percent into the hundreds place. For example 40% of 101, you would do .40 x 101 to get 40.4
