Question

PLEASE HELP ME pls simplify this ​

Answer 1

Answer:

c

Step-by-step 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

Answer:

C

Step-by-step 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

$\frac{15}{4}$ - $\frac{19}{8}$

The denominators must be common before subtracting

= $\frac{15(2)}{4(2)}$ - $\frac{19}{8}$

= $\frac{30}{8}$ - $\frac{19}{8}$ = $\frac{11}{8}$ → C
