0<x<1 and 0<y<1
x>0 so x is positive and y>0 so y is also positive.
When you multiply two positive numbers you always get a positive number, so the product of x and y must be positive, or greater than 0.
xy>0 - it must be true
xy<0 - it can't be true
Also when you divide a positive number by a positive number you always get a positive number, so the quotient of x and y must be positive.
x/y<0 - it can't be true
D and E can be true, but don't have to. It depends on the values of x and y. If x>y, then x-y>0 is true and x-y<0 isn't true; if x<y, then x-y>0 isn't true and x-y<0 is true.
Therefore, only A <u>must</u> be true.

Answer:
see explanation
Step-by-step explanation:
(1)
To find the unit rate divide the amount by 3
$3.84 ÷ 3 = $1.28 ← unit rate
(2)
Using proportion
$45 → 4 months
$180 → 4 × 
= 
= 16 months
(3)
sum the parts of the ratio, 8 + 1 = 9 parts
Divide 90 by 9 to find the value of one part
90 ÷ 9 = 10 ← value of 1 part
Thus
8 × 10 = 80
