Answer:
235674 is divisible by both 3 and 9.
Step-by-step explanation:
In this question you can apply divisibility rule of 3 and 9.
Divisibility rule of 3 is that number is said to be divisible by 3 if the sum of the digits of a number is divisible by 3.
Divisibility rule of 9 is that number is said to be divisible by 9 if the sum of the digits of a number is divisible by 9.
2+3+5+6+7+4= 27
27 is divisible by 3 and 9, therefore 235674 is divisible by both 3 and 9.
7+8+0+1+5 = 21
21 is divisible by 3 but not by 9, therefore 78015 is divisible by only 3 not by 9
