    (a) False as 6 is divisible by 3, but not by 9.

    (b) True, as 9 = 3 x 3 Therefore, if a number is divisible by 9, then it will also be divisible by 3.

    (c) False as 30 is divisible by 3 and 6 both, but it is not divisible by 18.

    (d) True as 9 x 10 = 90 Therefore, If a number is divisible by 9 and 10 both, then it will also be divisible by 90.

    (e) False as 15 and 32 are co-primes and also composite.

    (f) False as 12 is divisible by 4, but not by 8.

    (g) True, as 8 = 2 x 4 Therefore if a number is divisible by 8, then it will also be divisible by 2 and 4.

    (h) True as 2 divides 4 and 8 as well as 12. (4 + 8 = 12)

    (i) False as 2 divides 12, but not divide 7 and 5.
