## MP Board Class 6th Maths Solutions Chapter 6 Integers Ex 6.3

Question 1.

Find

(a) 35 – (20)

(b) 72 – (90)

(c) (-15) – (-18)

(d) (-20) – (13)

(e) 23 – (- 12)

(f) (-32) – (-40)

Solution:

(a) 35 – 20 = 15

(b) 72 – 90 = -18

(c) (-15) – (-18) = -15 + 18 = 3

(d) (-20) – (13) = -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)

Solution:

(a) < : (-3) + (-6) = -3 – 6 = -9

(-3) – (-6) = -3 + 6 = 3

Since, -9 < 3

∴ (-3) + (-6) < (-3) – (-6) (b) >: (-21) – (-10) = -21 + 10 = -11

(-31)+ (-11) = -31 – 11 = -42

Since, -11 > -42

(-21) – (-10) > (-31) + (-11)

(c) >: 45 – (-11) = 45 + 11 = 56

57 + (-4) = 57 – 4 = 53

Since, 56 > 53

45 – (-11) > 57 + (-4)

(d) >: (-25) – (-42) = -25 + 42 = 17

(-42) – (-25) = -42 + 25 = -17

Since, 17 > -17

∴ (-25) – (-42) > (-42) – (-25)

Question 3.

Fill in the blanks.

(a) (-8) + ___ = 0

(b) 13 + ___ = 0

(c) 12 +(-12) = ___

(d) (-4) + ___ = -12

(e) __- 15 = – 10

Solution:

(a) 8 : (-8) + 8 = 0

(b) -13 : 13 + (-13) = 0

(c) 0 : 12 + (-12) = 0

(d) -8 : (-4) + (-8) = -12

(e) 5 : 5 – 15 = -10

Question 4.

Find

(a) (-7) – 8 – (-25)

(b) (-13) + 32 – 8 – 1

(c) (- 7) + (- 8) + (- 90)

(d) 50 – (- 40) – (- 2)

Solution:

(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
