Exercise 6.3 - Chapter 6 Integers class 6 ncert solutions Maths - SaraNextGen [2024]


Question 1:

Find:

(a) 35 − (20) (b) 72 − (90)

(c) (− 15) − (− 18) (d) (− 20) − (13)

(e) 23 − (− 12) (f) (− 32) − (− 40)

Answer:

(a) 35 − 20 = 15

(b) 72 − 90 = −18

(c) −15 − (−18) = − 15 + 18 = 3

(d) − 20 − 13 = −33

(e) 23 − (−12) = 23 + 12 = 35

(f) (−32) − (−40) = −32 + 40 = 8

Question 2:

Fill in the blanks with >, < or = sign.

(a) (− 3) + (− 6) _____ (− 3) − (− 6)

(b) (− 21) − (− 10) _____ (− 31) + (− 11)

(c) 45 − (− 11) _____ 57 + (− 4)

(d) (− 25) − (− 42) _____ (− 42) − (−25)

Answer:

(a) (−3) + (−6) = −9

(−3) − (−6) = − 3 + 6 = 3

−9 < 3

Hence, (− 3) + (− 6) https://img-nm.mnimgs.com/img/study_content/curr/1/6/1/6/2030/Exercise%206_html_1a25fe66.gif  (− 3) − (− 6)

(b) − 21 − (−10) = − 21 + 10 = −11

− 31 + (−11) = −42

−11 > −42

(−21) − (−10) https://img-nm.mnimgs.com/img/study_content/curr/1/6/1/6/2030/Exercise%206_html_7ce9bbb2.gif  (−31) + (−11)

(c) 45 − (−11) = 45 + 11 = 56

57 + (−4) = 57 − 4 = 53

56 > 53

45 − (−11) https://img-nm.mnimgs.com/img/study_content/curr/1/6/1/6/2030/Exercise%206_html_7ce9bbb2.gif 57 + (−4)

(d) (−25) − (−42) = − 25 + 42 = 17

− 42 − (−25) = − 42 + 25 = −17

17 > −17

(−25) − (−42) https://img-nm.mnimgs.com/img/study_content/curr/1/6/1/6/2030/Exercise%206_html_7ce9bbb2.gif  (−42) − (−25)

Question 3:

Fill in the blanks.

(a) (− 8) + _____ = 0

(b) 13 + _____ = 0

(c) 12 + (− 12) = _____

(d) (− 4) + _____ = − 12

(e) _____ − 15 = − 10

Answer:

(a) − 8 + 8 = 0

(b) 13 + https://img-nm.mnimgs.com/img/study_content/curr/1/6/1/6/2032/Exercise%206_html_m437d1d28.gif  = 0

(c) 12 + (−12) = https://img-nm.mnimgs.com/img/study_content/curr/1/6/1/6/2032/Exercise%206_html_m78a96eab.gif

(d) − 4 + (−8) = −12

(e) 5 − 15 = −10

Question 4:

Find:

(a) (− 7) − 8 − (− 25)

(b) (− 13) + 32 − 8 − 1

(c) (− 7) + (− 8) + (− 90)

(d) 50 − (− 40) − (− 2)

Answer:

(a) − 7 − 8 − (−25) = − 7 − 8 + 25 = − 15 + 25 = 10

(b) (−13) + 32 − 8 − 1 = − 13 + 32 − 8 − 1 = 32 − 22 = 10

(c) (−7) + (−8) + (−90) = − 7 − 8 − 90 = −105

(d) 50 − (−40) − (−2) = 50 + 40 + 2 = 92
