:
The divisibility rule for 2 is:
If the number is even, it's divisible by 2.
:
The divisibility rule for 3 is:
If the sum of the digits are divisible by 3, then the number is divisible by 3.
:
The divisibility rule for 5 is:
If the number ends in a 0 or 5, then the number is divisible by 5.
:
925 is odd so the number is not divisible by 2.
the number ends in 5 so the number is divisible by 5, 925/5=185.
9+2+5=16, 16 is not divisible by 3, so 925 is not divisible by 3.
:
165 is odd so the number is not divisible by 2.
ends in 5, therefore 165 is divisible by 5. 165/5=33.
1+6+5=12, 12 is divisible by 3, 12/3=4, therefore 165 is divisible by 3. 165/3=55.
:
351 is odd therefore the number is not divisible by 2.
does not end in 0 or 5, therefore 351 is not divisible by 5.
3+5+1=9, 9 is divisible by 3, 9/3=3, therefore 351 is divisible by 3. 351/3=117.
:
1,495 is odd therefore 1,495 is not divisible by 2.
ends in 5, therefore 1,495 is divisible by 5. 1,495/5=299.
1+4+9+5=19, 19 is not divisible by 3, therefore 1,495 is not divisible by 3.
Happy Calculating!!!
