Sagot :
Answer:
A
B and C
D
D
A
B
C
Explanation:
#2 cause it doesn't end in 5 or 0
#3 coz it's divisible by 2 and 3
#4 coz 27 and 18 are divisible by 9
#5 coz the last two digits aren't divisible by 4
#6 when you add up the digits, it's divisible by 3
Answer:
1. If the last two digits form a number divisible by 4, the number is + also. 5 If the last digit is a 5 or a 0, the number is divisible by 5. 6 If the number is divisible by both 3 and 2, it is also divisible by 6.
2. NOTHING
3. A number is divisible by 6 if it is divisible by 2 and 3 both. Consider the following numbers which are divisible by 6, using the test of divisibility by 6: 42, 144, 180, 258, 156. [We know the rules of divisibility by 2 if the unit's place of the number is either 0 or multiple of 2].
4. List of Numbers Divisible by 9. There are 11 numbers less than 100 that are divisible by 9: 9, 18, 27, 36, 45, 63, 72, 81, 90, and 99.
5. According to the divisibility rule of 3, a number is said to be divisible by 3 if the sum of all digits of that number is divisible by 3. For example, the number 495 is exactly divisible by 3. The sum of all digits are 4 + 9 + 5 = 18 and 18 is exactly divided by 3.
6. If a number ends in 0 or 5, the number is divisible by 5.
