When you add or subtract common fraction, you must use a common denominator.

Since 2 divides evenly into 8 (4 times), use 8 as the common denominator.

Change 1/2 into a faction with a denominator of 8 by multiplying 1/2 x 4/4, giving you 4/8

-3 5/8  -  1 1/2       --->     - 3 5/8 - 1 4/8

Since these are both negative, add them together, giving you -4 9/8.

9/8  =  1 1/8, so the answer is -5 1/8
