type a digit that makes this statement true. 6,243,82□ is divisible by 3.
Answer
Explanation:
Step1: Recall divisibility rule of 3
A number is divisible by 3 if the sum of its digits is divisible by 3.
Step2: Calculate sum of known digits
The sum of the digits 6 + 2+4 + 3+8 + 2=25.
Step3: Find possible digits
We need to find a digit (x) such that (25 + x) is divisible by 3. Let (25+x = 3n), where (n) is an integer. When (n = 9), (3n=27) and (x = 27 - 25=2); when (n = 10), (3n = 30) and (x=30 - 25 = 5); when (n = 11), (3n=33) and (x = 33 - 25=8).
Answer:
2, 5, 8
