Determine the quotient of 2/3 divided by 4 using the standard algorithm. explain how the model and the standard algorithm are related. me solve this

Not sure if this is what ur looking for but to divide a fraction by something, multiply it by the reciprocal.
So it becomes 2/3 x 1/4.
Then multiply the numerators by numerators and the denominators by denominators so it becomes (2x1)/(3x4) = 2/12 which reduces to 1/6

11/2.2 = 5 inches for the length 8.5/2.2= 3.86 inches for the width

Do you need with the x value for the minimum? its always between the two intercepts for a parabola
