[C] If a number is divisible by both 2 and 3, then it is not divisible by 6.
-----
First, lets check the other answer choices.
-----
A number ending in 0 or 5 is always divisible by 5.
10 / 5 = 2
165 / 5 = 33
210 / 5 = 42
355 / 5 = 71
780 / 4 = 156
This statement is TRUE.
-----
A number ending in 0 is always divisible by 10.
10 / 10 = 1
100 / 10 = 10
150 / 10 = 15
470 / 10 = 47
690 / 10 = 69
This statement is TRUE.
-----
If a number is divisible by both 2 and 3, then it is not divisible by 6.
Take 18 for example:
18 / 2 = 9
18 / 3 = 6
18 / 6 = 3
Take 60 for example:
60 / 2 = 30
60 / 3 = 20
60 / 6 = 10
This statement is TRUE not false.
-----
Odd numbers are not divisible by 2.
This statement is correct because no odd number is divisible by 2.
5 / 2 = 2.5
7 / 2 = 3.5
9 / 2 = 4.5
11 / 2 = 5.5
13 / 2 = 6.5
This statement is TRUE.
