When 100 is divided by 45, what is the remainder?
A10
B0
C5
D45
Answer & Solution
Correct answer: A. 10
The greatest multiple of 45 that is at most 100 is (2)(45) = 90. The remainder is 100 - 90 = 10. So 100 = (2)(45) + 10, quotient 2, remainder 10. Option B would require 45 to divide 100 exactly, which it does not.
