Write all the integers between the given pairs, in increasing order. Class 6

Question 1.

Write all the integers between the given pairs, in increasing order. Class 6

(a) 0 and - 7

(b) - 4 and 4

(c) - 8 and - 15

(d) - 30 and - 23

Solution:

(a) -6, -5, -4, -3, -2 and -1.

(b) -3, -2, -1, 0, 1, 2, 3.

(c) -14, -13, -12, -11, -10, -9.

(d) -29, -28, -27, -26, -25, -24.

Question 2.

Give three numbers such that their sum is - 8. Class 6

Solution:

Three numbers can be -12, + 8 and -4. (There can be many other such numbers).

Question 3.

There are two dice whose faces have these numbers: -1,2, - 3,4, - 5,6. The smallest possible sum upon rolling these dice is -10 = (- 5) + (- 5) and the largest possible sum is 12 = (6) + (6). Some numbers between (-10) and (+ 12) are not possible to get by adding numbers on these two dice. Find those numbers. Class 6

Solution:

Numbers between (-10) and (+12) which are not possible to get by adding numbers on these dice are : -9, -7, -5, 0, 2, 7, 9 and 11.
