Answer 1

Answer:

1. non of them are divisible by 8

( the last 3 numbers should be divisible by 8. if it is then the whole number is divisible by 8)

314= 314÷8 = 39.25

8413= 413 ÷8 = 51.625

7134= 314÷8 = 39.25

2.last number is divisible by 9

(sum of all digits in the number should be divisible by 9.if it is then the number is divisible by 9)

7+3+1+4= 15

3+4+7+8= 22

4+5+7+2+1+8= 27 divisible by 9

3.last number is divisible by 4

( the last 2 number should be divisible by 4. if it is then the number is divisible by 4)

2053= 53÷4 =13.25

1523= 23÷4 = 6.25

9412= 12÷4= 3 divisible by 4

4. all number are divisible by 11

( if the difference between the sum of digits in the odd place is divisible by 11 then the number is divisible by 11)
