w= 4/3x
y= 3/4x
w/y=( 4/3x)/(3/4x) = (4/3x)(4/3x) = 16/9x^2
Quantity A
w/y = 1.8x^2 since x can be any number not zero
Quantity A is always greater

Hi, isn't the "X" would be cancelled out when w is divided by y?
Since
W = (4x/3) aka 4/3 * x
Y = (3x/4) aka 3/4 * x
W/Y = (4x/3) / (3x/4)
= (4x/3) * (4/3x) aka [(4/3)*x] * [(4/3)*x^-1]
= 16/9
#x^1*x^-1=x^0=1
