Maths 2 Marks

Given G is 3 and C is −1
∴ The number line becomes

A represents −3 and K represents 7

This representation is correct as the numbers are marked at equal intervals in the correct order.

This representation is wrong.
Because the numbers are not continuously marked as −6, −5, −4, −3, −2, −1, 0, 1, 2, 3, 4, 5, 6

This is the correct representation of Integers

The representation is wrong.
– 2 is misplaced in the number line.

14, 27, 15, −14, −9, 0, 11, −17
⇒ Separating the positive integers 14, 27, 15, 11 and negative integers −14, −9, −17
⇒ Arranging in descending order we get the positive integers 27, 15, 14, 11 and the
negative integers −9, −14, −17.
⇒ ‘0’ is neither positive nor negative and so it stand in middle.
⇒ ∴ The numbers in descending order: 27, 15, 14, 11, 0, −9, −14, −17

−99, −120, 65, −46, 78, 400, −600
⇒ Separating the positive integers 65, 78, 400 and negative integers −99, −120, −46, −600
⇒ Arranging the positive integers in descending order as 400, 78, 65 and the negative integers in descending order −46, −99, −120, −600.
⇒ The numbers in descending order: 400, 78, 65, −46, −99, −120, −600.

111, −222, 333, −444, 555, −666, 7777, −888
⇒ Separating the positive integers 111, 333, 555, 7777 and negative integers −222, −444, −666, −888
⇒ Arranging the positive integers in descending order as 7777, 555, 333, 111 and negative integers in descending order as −222, −444, −666, −888
⇒The numbers in descending order: 7777, 555, 333, 111, −222, −444, −666, −888
