-3 > -5

Since 3 is smaller than 5, -3 is greater than -5

(iii) -5, 2

2 > -5

This is because every positive integer is greater than every negative integer.

(iv) -16, 8

8 > -16

This is because every positive integer is greater than every negative integer.

(iii) 36 > 0 > -5 > -71 > -81

(iv) 413 > 102 > -7 > -365 > 515

Question 10:

Using the number line, write the integer which is

(i) 4 more than 6

(ii) 5 more than -6

(iii) 6 less than 2

(iv) 2 less than -3

Solution:

(i) 4 more than 6

We want an integer that is 4 more than 6. So, we will start from 6 and proceed 4 steps to the right to obtain 10. (ii) 5 more than -6

We want an integer that is 5 more than -6. So, we will start from -6 and proceed 5 steps to the right to obtain -1. (iii) 6 less than 2

We want an integer that is 6 less than 2. So, we will start from 2 and proceed 6 steps to the left to obtain -4. (iv) 2 less than -3

We want an integer that is 2 less than -3. So, we will start from -3 and proceed 2 steps to the left to obtain -5. Question 11:

For each of the following statements, write (T) for true and (F) for false:

(i) The smallest integer is zero.

(ii) Zero is not an integer.

(iii) The opposite of zero is zero.

(iv) -10 is greater than -6

(v) The absolute value of an integer is always greater than the integer.

(vi) 0 is larger than every negative integer.

(vii) Every negative integer is less than every natural number.

(viii) The successor of -187 is -188.

(ix) The predecessor of -215 is -214.

Solution:

(i) False

This is because 0 is greater than every negative integer.

(ii) False

0 is an integer as we know that every whole number is an integer and 0 is a whole number.

(iii) True

0 is an integer that is neither positive nor negative. So, the opposite of zero is zero.

(iv) False

Since 10 is greater than 6, -10 is smaller than -6.

(v) True

This is because an absolute value is a positive number. For example, -2 is an integer, but its absolute value is 2 and it is greater than -2.

(vi) True

This is because all negative integers are to the left of 0.

(vii) True

This is because natural numbers are positive and every positive integer is greater than every negative integer.

(viii) False

This is because the successor of -187 is equal to -186 (-187 + 1). In succession, we move from the left to the right along a number line.

(ix) False

This is because the predecessor of -215 is -216 (-215 – 1). To find the predecessor, we move from the right to the left along a number line.

Question 12:

Find the value of

(i) |-9|

(ii) |-36|

(iii) |0|

(iv) |15|

(v) -|-3|

(vi) 7 + |-3|

(vii) |7 – 4|

(viii) 8 – |-7|

Solution:

(i) The value of |-9| is 9.

(ii) The value of |-36| is 36.

(iii) The value of |0| is 0.

(iv) The value of |15| is 15.

(v) The value of |-3| is -3.

(vi) 7 + |-3|

= 7 + 3 = 10

(vii) |7 – 4|

= |3| = 3

(viii) 8 – |-7|

= 8 – 7 = 1

Question 13:

(i) Write five negative integers greater than -7.

(ii) Write five negative integers less than -20.

Solution:

(i) Every negative integer that is to the right of -7 is greater than -7.

So, five negative integers that are greater than -7 are -6, -5, -4, -3, -2 and -1.

(ii) Every negative integer that is to the left of -20 is less than -20.

So, five negative integers that are less than -20 are -21, -22, -23, -24 and -25.
