Question

PLEASE HELP ME pls simplify this ​

Answer 1

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 2

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
