Answer:

Required ration which represent the situation = \frac{-13}{2}

Step-by-step explanation:

Given: Cars in parking lot decreases at rate of 13 cars every 2 minutes.

To find: Rational Number which represent given information

Rational Number is a number in form of  \frac{p}{q} where p be any integer and q is non zero integer.

So from given information

No of cars decreases in 2 minutes = 13 cars

So, No of cars decreases in 1 minute = \frac{13}{2}

Therefore rate at which cars decreasing in parking lot is  \frac{13}{2}  cars/min.

Since it is decreasing, ration which represent it must be equal to \frac{-13}{2}

Therefore, Required ration which represent the situation = \frac{-13}{2}
