20 na bilang ng "9"

Sa 1-digit (1–9): Isa lang ang 9

Sa 2-digit numbers (10–99):

  • Numbers with 9 in the tens place: 90–99 → 10 numbers
  • Numbers with 9 in the ones place: 19, 29, 39, 49, 59, 69, 79, 89 → 8 numbers
  • Note: 99 is counted twice (both tens and ones), so no need to add again.

Total: 1 (single-digit) + 9 (ones place) + 10 (tens place) = 20
