When the divisor in a division problem is more than one digit.Example: 456/23. What is divisibility? When one number can be divided by another and the result is an exact whole number. Example: 15 is divisible by 3, because 15 ÷ 3 = 5 exactly But 9 is not divisible by 2 because 9 ÷ 2 is 4 with 1 left over. What is numerator?
