(iv) 2398

(v) 79532

(vi) 13576

(vii) 46821

(viii) 84663

(ix) 66669

Answer :

(i) 94


We know that if units place digit is divisible by 2 then our given number is divisible by 2.


Here units place is 4, which is divisible by 2.


Hence, 94 is divisible by 2.


(ii) 570


We know that if units place digit is divisible by 2 then our given number is divisible by 2.


Here units place is 0, which is divisible by 2.


Hence, 570 is divisible by 2.


(iii) 285


We know that if units place digit is divisible by 2 then our given number is divisible by 2.


Here units place is 5, which is not divisible by 2.


Hence, 570 is not divisible by 2.


(iv) 2398


We know that if units place digit is divisible by 2 then our given number is divisible by 2.


Here units place is 8, which is divisible by 2.


Hence, 2398 is divisible by 2.


(v) 79532


We know that if units place digit is divisible by 2 then our given number is divisible by 2.


Here units place is 8, which is divisible by 2.


Hence, 79532 is divisible by 2.


(vi) 13576


We know that if units place digit is divisible by 2 then our given number is divisible by 2.


Here units place is 6, which is divisible by 2.


Hence, 13576 is divisible by 2.


(vii) 46821


We know that if units place digit is divisible by 2 then our given number is divisible by 2.


Here units place is 1, which is not divisible by 2.


Hence, 46821 is not divisible by 2.


(viii) 84663


We know that if units place digit is divisible by 2 then our given number is divisible by 2.


Here units place is 3, which is not divisible by 2.


Hence, 84663 is not divisible by 2.


(ix) 66669


We know that if units place digit is divisible by 2 then our given number is divisible by 2.


Here units place is 9, which is not divisible by 2.


Hence, 66669 is not divisible by 2.
