A number is divisible by 3 if the sum of the digits in the number is divisible by 3
True or False

Solution:

A number is divisible by 3 if the sum of the digits in the number is divisible by 3. The statement is TRUE.

Consider 156: Let us show that it is divisible by 3

Here sum of the digits = 1 + 5 + 6 = 12

12 is divisible by 3

156 = 100 + 50 + 6

= (1 + 5 + 6) + (99 + 45)

= (1 + 5 + 6) + 3 (33 + 15)

156 and (33 + 15) are both divisible by 3

Sum, 1 + 5 + 6 = 12 is divisible by 3

Therefore, it is true.

A number is divisible by 3 if the sum of the digits in the number are divisible by 3
True or False

Summary:

A number is divisible by 3 if the sum of the digits in the number are divisible by 3 is true.
