Answer:

Step-by-step explanation:

Multiply and divide by the conjugate.
The conjugate is the denominator with the sign of the complex number the opposite of the denominator.

Quotient = 
(45 1/4) / 2 = (181/4) / 2 = 181/4 * 1/2 = 181/8 = 22 5/8 inches
(47 1/4) / 2 = (189/4) / 2 = 189/4 * 1/2 = 189/8 = 23 5/8 inches
2/2 = 1 inch thick
(5 3/4) / 2 = 23/4 * 1/2 = 23/8 = 2 7/8 inches
(3 1/2) / 2 = 7/2 * 1/2 = 7/4 = 1 3/4 inches
