Answer:
C.) -2 1/8
Step-by-step explanation:
-5 5/8 can be rewritten as - 45/8
3 1/2 can be rewritten as 7/2
Now we need it so that the denominator is equal.
so, we are going to multiply 7 and 2 by 4 to get 2 to 8 and 7 to 28.
7/2 = 28/8
Now subtract.
28/8 - 45/8 = - 17/8
Now we simplify.
Since 8 x 2 equals 16, we subtract 16 from 17 and get 1 so, the whole number is 2 and the fraction is 1/8, so the answer is -2 1/8
