The square root of 140/9 can be simplified as follows:
First, we simplify the fraction under the square root sign:

√(140/9) = √(4*35/3^2)

Next, we can split the square root:

√(4*35/3^2) = √(4)/√(3^2) * √(35)

Simplifying further:

√(4)/√(3^2) * √(35) = 2/3 * √(35)

Therefore, the simplified expression is 2/3 * √35.

To find the quotient of -7 ÷ fourteen-thirds, we can multiply the dividend by the reciprocal of the divisor.

The reciprocal of fourteen-thirds is three-fourteenths.

-7 ÷ fourteen-thirds can be written as -7 * (3/14).

Multiplying these values:

-7 * (3/14) = -21/14.

Thus, the quotient is -21/14, which can also be simplified to -3/2.

To determine the best buy among the given options, we need to calculate the cost per ounce for each cereal.

For the first option, 28 oz. of cereal for $4.29, the cost per ounce is 4.29/28 = 0.153%

For the second option, 32 oz. of cereal for $4.59, the cost per ounce is 4.59/32 = 0.143%

For the third option, 36 oz. of cereal for $4.79, the cost per ounce is 4.79/36 = 0.133%

For the fourth option, 24 oz. of cereal for $3.59, the cost per ounce is 3.59/24 = 0.149%

Comparing the cost per ounce, we can see that the cereal with the lowest cost per ounce is the third option: 36 oz. of cereal for $4.79.

Therefore, the best buy among the given options is 36 oz. of cereal for $4.79.
