 From 21 to 99 you have to add “e” (which means and) between the tens and the unities.

 Use the word “cem” for 100 and the word “cento” for number from 101 to 199.

Example:

100. cem  

101. cento e um  

138. cento e trinta e oito  

199. cento e noventa e nove  

200, 300, 400, 500, 600, 700, 800, 900 have feminine and masculine forms. They must agree in gender and number with the noun. Observe that when they are written in the masculine form they end in “os” and when they are written in the feminine from they end in “as”

 Compare:

• 200 men: duzentos homens / 200 women: duzentas mulheres
• 330 cars: trezentos e trinta carros / 330 houses: trezentas e trinta casas.
• 467 boys: quatrocentos e sessenta e sete meninos / 467 girls: quatrocentas e sessenta e sete meninas.

 Use “e” (which means “and”) to separate hundreds, tens, and unities.

Example:

25. vinte e cinco

125 cento e viente e cinco

34 trinta e quatro

234. duzentos e trinta e quatro

75. setenta e cinco
