To find the quotient of -7 divided by fourteen-thirds, we need to divide -7 by the reciprocal of fourteen-thirds.
The reciprocal of fourteen-thirds is three-fourteenths.
So, the quotient is -7 * three-fourteenths, which simplifies to -21/14 or -3/2.
Therefore, the correct option is: negative three-halves.

Responses
28 oz. of cereal for $4.29
28 oz. of cereal for $4.29
32 oz. of cereal for $4.59
32 oz. of cereal for $4.59
36 oz. of cereal for $4.79
36 oz. of cereal for $4.79
24 oz. of cereal for $3.59
To determine the best buy, we need to compare the prices per ounce of cereal.
For the first option: 4.29 / 28 = 0.1532 dollars per ounce
For the second option: 4.59 / 32 = 0.1434 dollars per ounce
For the third option: 4.79 / 36 = 0.1331 dollars per ounce
For the fourth option: 3.59 / 24 = 0.1496 dollars per ounce
The option with the lowest price per ounce is the third option: 36 oz. of cereal for $4.79. Therefore, that is the best buy.
