Answer:

c

Explanation:

because of the absolute number of -12-3 = 15. simply 15/4 to have the same denamenator. so it's 30/8. 30/8 - 19/8 is 11/8

Answer:

C

Explanation:

Note that the absolute value always returns a positive value, that is

| - a | = | a | = a, hence

| - 12 - 3 | = | - 15 | = 15 and

| 23 - 42 | = | - 19 | = 19

Thus the subtraction reduces to


(15)/(4) -
(19)/(8)

The denominators must be common before subtracting

=
(15(2))/(4(2)) -
(19)/(8)

=
(30)/(8) -
(19)/(8) =
(11)/(8) → C
