1 ÷ 3 = 0 r 3 → first multiple of 3 in the range 1-81 is 1 x 3 = 3
81 ÷ 3 = 27 → last multiple of 3 in the range 1-81 is 27 x 3 = 3
→ there are 27 - 1 + 1 = 27 multiples of 3 in the range 1-81, which are:
3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, 60, 63, 66, 69, 72, 75, 78, 81.
