NCERT Solutions for Class 7 Maths Chapter 1 Integers Exercise 1.2<\/h2>\n

Question 1:
\nWrite down a pair of integers whose:
\n(a) sum is – 7
\n(b) difference is – 10
\n(c) sum is 0
\nAnswer:
\n(a) – 15 and 8
\nsum = – 15 + 8 = – 7<\/p>\n

(b) – 30 and – 20
\nDifference = – 30 – (- 20)
\n= -30 + 20 = – 10<\/p>\n

(c) – 12 and + 12
\nDifference = – 12 + (12)
\n= -12 + 12 = 0<\/p>\n

\"NCERT<\/p>\n

Question 2.
\n(a) Write a pair of negative integers whose difference gives 8.
\n(b) Write a negative integer and a positive integer whose sum is – 5.
\n(c) Write a negative integer and a positive integer whose difference is – 3.
\nAnswer:
\n(a) – 13 and – 21
\nDifference = -13 – (- 21)
\n= – 13 + 21 = 8<\/p>\n

(b) – 15 and 10
\nsum = – 15 + 10 = – 5
\n(c) – 1 and 2
\nDifference = – 1 – (+ 2)
\n= – 1 – 2 = – 3<\/p>\n

Question 3.
\nIn a quiz, team A scored – 40, 10, 0 and team B scored 10, 0, – 40 in three successive rounds. Which team scored more? Can we say that we can add integers in any order?
\nAnswer:
\nTotal score of team A = (- 40) + 10 + 0
\n= – 40 + 10 + 0 = – 30
\nTotal score of team B=10 + 0 + (- 40)
\n= 10 + 0 – 40 = 10 – 40 = – 30
\nSo, both the team scored equal. Yes, we can say that we can add integers in any order.<\/p>\n

\"NCERT<\/p>\n

Question 4.
\nFill in the blanks to make the following statements true:
\n(i) (- 5) + (- 8) = (- 8) + (………………)
\n(ii) – 53 + …………… = – 53
\n(iii) 17 + ……………… = 0
\n(iv) [13 + (- 12)] + (…………..) = 13 + [(- 12) + (- 7)]
\n(v) (- 4) + [15 + (- 3)] = [- 4 + 15] + …………….
\nAnswer:
\n(i) (- 5) + (- 8) = (- 8) + (- 5)
\n(ii) – 53 + 0 = – 53
\n(iii) 17 + (- 17) = 0
\n(iv) [13 + (- 12)] + (- 7) = 13 + [(-12) + (- 7)]
\n(v) (-4)+ [15 +(-3)] = [-4 + 15] + (- 3)<\/p>\n","protected":false},"excerpt":{"rendered":"
