Answer: 5 cookies 2 days
Explanation:
In integers , we use negative signs to represent "" decrease , fall , loss or drp ".
Given : The cookies in Sarah's cookie jar decrease by 5 cookies every 2 days.
Since there is fall of the number of cookies by 5 cookies every 2 days, in integers we represent the scenario with negative sign.
i.e. −5 cookies 2 days OR 5 cookies −2 days OR − 5 cookies 2 days
i.e. the rational number does not describes the scenario (Positive sign)= 5 cookies 2 days
