**Answer: Option A. ->**5

The distance between any two consecutive numbers is 1 unit. So the distance between number 2 and 7 is 5 units.

**Answer: Option A. ->**Line Segment

In this hypothetical universe, each number is represented by dots such that the number of dots in that universe corresponds to the value of the number it represents in this universe.

Hence, to represent two, we use two dots. When we join two dots by a straight line, we get a line segment and nothing else, as shown.

**Answer: Option D. ->**Natural Number

When we add any two natural numbers, the answer is always a natural number.

For example: Take any two natural numbers say 5 and 7. Add them 5 + 7 = 12, 12 is also a natural number.

**Answer: Option A. ->**True

All natural numbers are whole numbers. When zero is included in the list of natural numbers it becomes a set ofwhole numbers.

**Answer: Option A. ->**subtracting

The predecessor of any number is the number that comes immediately before that number. The predecessor of any number can be obtained by subtracting one from it.

**Answer: Option C. ->**i and iii only

i)0 + 2 = 2 which is a whole number. Also, whole numbers are closed under addition. ii)0 ÷ 49843 = 0 which is a whole number. iii)98645 × 5678 = 5678 × 98645

This represents commutative property of multiplication.

**Answer: Option A. ->**True

If you divide something by 2 you divide that thing into 2 parts. If you divide something by 4 you divide that thing into 4 parts. Now if you divide something by 0, you cannot divide that thing into 0 parts. So a division by 0 is undefined and Rahuli s correct.
