There are one number is X, and another number is -9/10and sum is 2/3.
The inequality that describes the possible values of the expression is:

<h3>What is the lower bound of values of the expression?</h3>
The expression is given by:

To find the lower bound, we try to see when the expression is negative, hence:


Applying cross multiplication and simplifying the 3's, we have that:

From the bounds given, this expression will never be true, at most they can be equal, when:
a = b = 4.
Hence the lower bound of values of the expression is of 0.
<h3>What is the upper bound of values of the expression?</h3>
The expression is a subtraction, hence we want to maximize the first term and minimize the second.
Considering that the first term is direct proportional to b and inverse to a, and the second vice versa, we want to:
Then:

Hence the bounds are:

Answer:6/8 pounds
Step-by-step explanation:
2 1/4 - 1 1/2
- 2 times 4 plus 1 = 9/4
- 1 times 2 plus 1 = 3/2
9/4 - 3/2
-to subtract your fraction, you need to have the same denominator in each side
- 4 times 2 = 8 (this is your denominator)
- 4 times 3 = 12 (your right numerator)
- 2 times 9 = 18 (your left numerator)
18/8 - 12/8 = 6/8
