To solve this expression, we follow the order of operations (PEMDAS/BODMAS).
First, we simplify the expressions inside the parentheses:
1/2 (16 ÷ 4 + 4) ÷ (6 × 4 ÷ 8)
= 1/2 (4 + 4) ÷ (6 × 4 ÷ 8)
= 1/2 (8) ÷ (6 × 4 ÷ 8)
Next, we simplify the division within the numerator and denominator:
1/2 (8) ÷ (6 × 4 ÷ 8)
= 1/2 (8) ÷ (24 ÷ 8)
= 1/2 (8) ÷ (3)
= 1/2 * 8/3
= 8/6
Finally, we simplify the fraction:
8/6 = 4/3
Therefore, 1/2 (16 ÷ 4 + 4) ÷ (6 × 4 ÷ 8) simplifies to 4/3.

To evaluate the expression 260 − (−45) − 45, we can simplify it step by step.
First, let's tackle the double negative.
260 − (−45) − 45
= 260 + 45 − 45
Next, let's add and subtract.
= (260 + 45) − 45
= 305 − 45
= 260
Therefore, 260 − (−45) − 45 equals 260.

To determine the equivalent expression to 13 + (34 + 23), we just need to simplify the expression by applying the rule of parentheses.
13 + (34 + 23) = 13 + 57
Now, if we evaluate 13 + 57, we get:
13 + 57 = 70
Therefore, the expression equivalent to 13 + (34 + 23) is D) 34 - 23 + 13.
13 + (34 + 23) = 13 + 57
Now, if we evaluate 13 + 57, we get:
13 + 57 = 70
