O *número* 9 só aparece uma vez nesse intervalo.
Porém é necessário utilizar o *algarismo* nove 20 vezes para escrever todos os *números* de 1 a 100.
Abraço!

Se for o número de algarismos - 20
9,19,29,39,49,59,69,79,89,90 - 10 "noves"
91,92,93,94,95,96,97,98,99 - mais 10 "noves"
Se for "matematicamente" - 11 ( 11 * 9 = 99)
