Step-by-step explanation:
1. AS 3021 IS NOT DIVISIBLE BY 2
SO THE NUMBER IS NOT DIVISIBLE BY 6
DIVISIBILITY RULE: IF THE NUMER IS DIVISIBLE BY 2 AND 3 SO THE NUMER IS DIVISIBLE BY 6
2. 6+3+1+8=18, AS 18 IS DIVISIBLE BY 9 SO THE NUMBER 6318 IS DIVISIBLE BY 9
DIVISIBILITY RULE: BY ADDING ALL THE DIGITS OF THE NUMBER IF THE NUMBER IS DIVISIBLE BY 9 SO THE NUMBER IS DIVISIBLE BY 9
3. 2+9+6+0=17, AS THE NUMBER IS NOT DIVISIBLE BY 3 SO THE NUMBER 2960 IS NOT DIVISIBLE BY 3
DIVISIBILITY RULE: BY ADDING ALL THE DIGITS OF THE NUMBER IF THE NUMBER IS DIVISIBLE BY 3 SO THE NUMBER IS DIVISIBLE BY 3
4.9027 IS NOT DIVISIBLE BY 2
SO THE NUMBER IS NOT DIVISIBLE BY 6
DIVISIBILITY RULE: IF THE NUMER IS DIVISIBLE BY 2 AND 3 SO THE NUMER IS DIVISIBLE BY 6
5.7+0+1+2=10,AS THE NUMER IS NOT DIVISIBLE BY 3 SO THE NUMBER 7012 IS NOT DIVISIBLE BY 3
DIVISIBILITY RULE: BY ADDING ALL THE DIGITS OF THE NUMBER IF THE NUMBER IS DIVISIBLE BY 3 SO THE NUMBER IS DIVISIBLE BY 3
