If ⊗, O, ✓, and • represent some integers on number line, then descending order of these numbers is
a. •, ⊗, ✓, O
b. ⊗, •, ✓, O
c. O, ✓, ⊗, •
d. O, •, ⊗, ✓

Solution:

In the given number each division is placed at a distance of 1 unit apart. To determine the descending order of the marked numbers we need to first recall how descending order works. Arranging in descending order means arranging any data from the highest side to the lowest side.

Using the integers on number line properties we know that on the right side of zero we have all the positive integers and on the left side of zero we have all the negative integers.

So going by the same logic the descending order of these numbers is O, ✓, ⊗, •.

✦ Try This: Can you try finding the ascending order of the same numbers marked above

Using the integers on the number line rules and the facts about ascending order we can easily figure out the ascending order of these numbers. When any list has its values from smallest to largest, we say that the list is arranged in an ascending manner

If ⊗, O, ✓, and • represent some integers on the number line, then the descending order of these numbers is:  a. •, ⊗, ✓, O, b. ⊗, •, ✓, O c. O, ✓, ⊗, • d. O, •, ⊗, ✓

Summary:

According to the integers on the number line rule the descending order of these numbers is O, ✓, ⊗, •.
