1. A.

2. D.

3. C.

================================

Explanations:

1.) The answer is A. (6m) because 240 cm is 2.4m, 0.50 dm is 50 cm, and 5,000 mm is 5m, so 6m (6 meters) is the longest measurement.

2.) Answer is D. () because its value is 1. A. (-1) is negative 1, B. (3/8) equals 0.375, and C. (0.8) is just 80% of 1, meaning it is smaller than 1.

3.) The answer will be letter C. ( |19| ). This is because the absolute value is the distance between a number and zero. So if we will find the distance between -100 and 0, the answer will be positive 100. This is same with letter B. ( |-43| ). So the final answer would be letter C.
