Problem solving Key Points
1 A 3-digit number is made using three of the If a number is
numbers 0, 1, 2, 3, 4, and 5. If each digit can be divisible by both 2
used only once, how many numbers are divisible and 5, the digit in
by 2, 3, and 5? the ones place is 0.
2 The 5-digit number, 235 , is divisible by both 9 Since the number is
and 5. Find all the possible digits for and . divisible by 5,
must be 0 or 5.
