What is a fraction?
Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
We have:
The height of each story of an office building is 9 3/4 feet.
9 3/4 = 39/4 feet
The building has three underground levels for parking. A car is parked two levels below ground.
The elevation = 2(39/4) = 39/2
= 19 1/2 in mixed fraction

Elevation = -19 1/2
Thus, the elevation of the car’s tires relative to the ground level is -19 1/2 option (A) is correct.
