Explanation

Using repeated subtraction: 100 - 17 = 83 (1 necklace), 83 - 17 = 66 (2 necklaces), 66 - 17 = 49 (3 necklaces), 49 - 17 = 32 (4 necklaces), 32 - 17 = 15 (5 necklaces). 15 shells are not enough for another necklace. So 5 necklaces can be made.

Solution Steps

  1. Step 1: Total shells = 100

  2. Step 2: Shells per necklace = 17

  3. Step 3: 100 ÷ 17 = 5 remainder 15

  4. Step 4: 5 necklaces can be made with 15 shells remaining
