19. Which set of numbers is ordered correctly from least to greatest?

A. 0,-3,-[4],[-5],8
B. 8,[-5],-[4],-3,0
C. -[4],-3,0,[-5],8
D, [-5],-[4],-3,0,8 ••

Right.

Which set of rational numbers is correctly ordered from least to greatest?

Select one:

-0.5, -0.4, -0.3

-0.3, -0.4, -0.5

-0.5, -0.3, -0.4

The correct answer is B. 8,[-5],-[4],-3,0.

To determine the correct order of the set of numbers, we need to compare the numbers and arrange them from least to greatest. Let's analyze each option:

Option A: 0, -3, -[4], -[5], 8
Option B: 8, -[5], -[4], -3, 0
Option C: -[4], -3, 0, -[5], 8
Option D: -[5], -[4], -3, 0, 8

To compare the numbers, disregard any brackets (since they don't affect the order), and focus on the values inside the brackets.

Option A: 0, -3, 4, 5, 8
Option B: 8, 5, 4, -3, 0
Option C: 4, -3, 0, 5, 8
Option D: 5, 4, -3, 0, 8

Now we can arrange the numbers in ascending order:

Option A: -3, 0, 4, 5, 8
Option B: -3, 0, 4, 5, 8
Option C: -3, 0, 4, 5, 8
Option D: -3, 0, 4, 5, 8

By comparing the rearranged options, we can see that option D, [-5], -[4], -3, 0, 8, is correctly ordered from least to greatest.
