Answer 1

Step-by-step explanation:

a) 572

divisibility check by 3

add the no. 5+7+2 = 14 (14 is not divisible by 3 )

divisibility check by 9

add the no. 5+7+2 =14 (14 is not divisible by 9 ; so 572 is also not divisible by 9)

divisibility check by 10

last no. must be 0 (at one's place,) to be divisible by 10

divisibility check by 11

+5-7+2 = 0 It is divisible by 11, if we get 0 or multiple of 11, so the no. is also divisible by 11
