Question 51.

The greatest negative integer is ____ and the smallest positive integer is _____.

+1 and -1
-1 and +1
-1 and -1
+1 and +1

Discuss Question

Answer: Option B. -> -1 and +1
:
B

Observe a number line.

In negative numbers, as magnitude increases, value decreases.
Therefore, the largest negative integer is -1.
Similarly, in positive numbers, as magnitude increases, value increases.
Therefore, the smallest positive integer is 1.

Question 52.

The figure below represents a vertical number line. Which number does the point 'F' represent ?

+8
-7
-8
-9

Discuss Question

Answer: Option C. -> -8
:
C
In a vertical number line, the numbers above 0 are positive and the numbers below zero are negative.
Given, point D = +8. We can conclude that each division is 1 unit.
Point F is also 8 units away from '0' and below zero.
Hence the number represented by the point F is -8.

Question 53.

If we are at (-7) on the number line and go 9 units to the right, we would reach _____ number on the number line.

2
0
(-16)
(-1)

Discuss Question

Answer: Option A. -> 2
:
A
In the number line when we move towards right, the value increases.
Consider that we are at (-7) on the number line. If we go 9 units to the right then, we will reach 2 i.e. (-7) + 9 = 2 .

If We Are At (-7) On The Number Line and Go 9 Units To The ...

Question 54.

Which of the following integers are less than -9?

0, -1 ,-11 ,9 ,-9 ,99 ,-99 ,999 ,-999
-8, -7, -6, -5, -4, -11, -12, -13, -14
100, 1010,11, 1, 12, 122, 1222, 121212, 3
-11, -12, -151, -121, -11111, -12121212, -1345, -1111123

Discuss Question

Answer: Option D. -> -11, -12, -151, -121, -11111, -12121212, -1345, -1111123
:
D

-10,-11,-12,-13,-14,,-15,-16,-17,-18,-19,-20.......and so on are less than -9.
Hence, from the given options
-11, -12, -151, -121, -11111, -12121212, -1345, -1111123 are all less than -9.

Question 55.

Arrange in ascending order:

-1, -11 , 111 , -111 , 11 , 0 , 1

-1 , -11 , 111 , -111 , 11 , 0 , 1
-111 , -11 , -1 , 0 , 1 , 11 , 111
-1 , 11 , 111 , -111 , -11 , 0 , 1
1, -11 , -111 , 111 , 11 , 0 , -1

Discuss Question

Answer: Option B. -> -111 , -11 , -1 , 0 , 1 , 11 , 111
:
B

When considering negative numbers, the bigger the number, smaller is its value.
So, -111 is less than -11.
Similarly, -11 is less than -1.
Hence, among the given numbers, -111 is the smallest and 111 is the biggest number.
Ascending order of numbers is the arranging of numbers from smallest to largest.So, the given numbers in ascending order is -111, -11, -1, 0, 1, 11, 111.

Question 56.

Five negative integers greater than -10 are:

-11, -12, -13, -14, -15
-9, -8, -7, -11, -12
-6, -5, -4, -3, -2
0, 1, 2, 3, -14, -13

Discuss Question

Answer: Option C. -> -6, -5, -4, -3, -2
:
C

-9,-8,-7,-6,-5,-4,-3,-2,-1,0,1,2,3,4,5,6............ and so on, are greater than -10.

Question 57.

Fill in the blanks:

Farther a number is from 0 on the right, _____ is its value.

Farther a number is from 0 on the left, _____ is its value.

larger, smaller
smaller, larger
no change, smaller
larger, no change

Discuss Question

Answer: Option A. -> larger, smaller
:
A

As you move towards the right on the number line, the value increases and as you move towards the left on the numberline, the value decreases.
Hence,
farther a number is from 0 on the right, larger is its value.
Farther a number is from 0 on the left, smaller is its value.

Question 58.

Which of the following integer does not lie between -8 and +6 ?

-7
+7
-5
+3

Discuss Question

Answer: Option B. -> +7
:
B
The integers that lie between -8 and +6 are -7, -6, -5, -4, -3, -2 , -1, 0, 1, 2, 3, 4.
Hence from the given options, we can see that +7 does not lie between -8 and +6.

Question 59.

Statement 1: Zero is a positive number
Statement 2: Zero is a negative number

Statement 1 is true and Statement 2 is false
Statement 1 is false and Statement 2 is true
Both the statements are false
Both the statements are true

Discuss Question

Answer: Option C. -> Both the statements are false
:
C

Zero is the only number which is neither positive nor negative.

Question 60.

A building has 20 stairs above ground level and 20 stairs below ground level. If you are standing at the 16^th step below ground level, then how will you represent it mathematically?

You are at +16^th step.
You are at -16^th step.
You are at -4^th step.
You are at 4^th step.

Discuss Question

Answer: Option B. -> You are at -16^th step.
:
B

When we compare the stairs to a vertical number line, the ground level can be taken as zero,the stairs above the ground level are considered as positive integers and the stairs below the ground level are considered as negative inetgers. So, if you are standing at the 16^th step below ground level then, we can say that you are at -16^th step.
