alleryWhy do only the last two digits matter when testing divisibility by 4?
ABecause 10 is divisible by 4
BBecause 100 is divisible by 4
CBecause 4 has just two digits
DBecause 4 is an even number
Answer & Solution
Correct answer: B. Because 100 is divisible by 4
1. Hundreds, thousands and so on are multiples of 100.
2. Since 100 is divisible by 4, those parts add nothing to the remainder.
3. 10 is not divisible by 4, so one digit is not enough.
