Answer:

ANS 1)

a) 23-(-6+[ 8-{9-6} ] )

= 23+6+[-72+48]

= 29+[-24]

=29-24

= 5

b) 100-56÷7+15×2

= 44÷7+ 30

= 74÷7

= 10.57

ANS 2)

a) HCF of 60-72

= 2×2×2×3×3×5

= 2×2×3×5

b) HCF of 18 - 48

= 2×2×2×2×3×3

=2×2×3

ANS 4 )

a) 12+10/12

=12/12

= 1

b) 23+17/7

= 40/7

ANS 5)

a) True

b) False

c) False
