### CBSE Class 7 Integers Practice Worksheet

Q.1) Write the integer which is its own additive inverse.

Answer : The integer which is its own additive inverse is 0. This is because when you add 0 to itself, you get 0: 0 + 0 = 0.

Q.2) Write six distinct integers whose sum is 7.

Answer : Six distinct integers whose sum is 7 could be: -3, -2, -1, 0, 1, and 12. When you add these numbers together, you get: -3 + (-2) + (-1) + 0 + 1 + 12 = 7.

Q.3) Write the integer which is 4 more than its additive inverse.

Answer : The integer which is 4 more than its additive inverse is 4. This is because when you add 4 to its additive inverse (-4), you get 0: 4 + (-4) = 0

Q.4) Write the integer which is 2 less than its additive inverse.

Answer : The integer which is 2 less than its additive inverse is -1. This is because when you add 2 to its additive inverse (2), you get 0: (-1) + 2 = 1.

Q.5) Write two integers whose sum is less than both the integers.

Answer : Two integers whose sum is less than both integers could be -3 and -2. When you add these numbers together, you get: -3 + (-2) = -5, which is less than both -3 and -2.

Q.6) Find the product, using suitable properties:
(a) 26 × (– 48) + (– 48) × (–36)

Q.8) Find the sum of the pairs of integers:
(a)–6,–4      (b)+3,–4     (c)+4,–2

(a) (−6)+(−4)=−10(−6)+(−4)=−10
(b) (+3)+(−4)=−1(+3)+(−4)=−1
(c) (+4)+(−2)=+2(+4)+(−2)=+2

Q.9) Find the sum of –2 and –3, using the number line.

Q.10) Subtract : (i) 3 from –4 (ii) –3 from –4

(i) −4−3=−7−4−3=−7
(ii) −4−(−3)=−4+3=−1−4−(−3)=−4+3=−1

Q.11) Using the number line, subtract : (a) 2 from –3 (b) –2 from –3.

Q.12) How many integers are there between –9 and –2 ?

Answers : There are 8 integers between -9 and -2: -8, -7, -6, -5, -4, -3, -2, -1.

Q.13) Calculate: 1 – 2 + 3 – 4 + 5 – 6 + 7 – 8 + 9 – 10

This is an alternating series of positive and negative integers. When you group them in pairs, you get:

(1−2)+(3−4)+(5−6)+(7−8)+(9−10)=(−1)+(−1)+(−1)+(−1)+(−1)=−5(1−2)+(3−4)+(5−6)+(7−8)+(9−10)=(−1)+(−1)+(−1)+(−1)+(−1)=−5

So, the sum is -5.

Q.14) The pair of integers whose sum is –5
(b)1,–4 (b) –1,6 (c) –3,–2

Answer: The pair of integers whose sum is -5 is (a) 1, -4.
