Why learn numbers with questions and answers?
Numbers appear everywhere: prices, bus schedules, phone numbers, ages, dates, and quantities. Practicing numbers in question-and-answer format trains listening, speaking, and comprehension at the same time. Instead of memorizing lists, you learn how Brazilians actually ask and respond, which makes your learning faster and more natural.
Basic cardinal numbers (0–20)
Start with the most common numbers. Practice asking and answering simple questions so the words become automatic.
zero – 0
um – 1 (masculine) / uma – 1 (feminine)
dois – 2 (masculine) / duas – 2 (feminine)
três – 3
quatro – 4
cinco – 5
seis – 6
sete – 7
oito – 8
nove – 9
dez – 10
onze – 11
doze – 12
treze – 13
quatorze – 14
quinze – 15
dezesseis – 16
dezessete – 17
dezoito – 18
dezenove – 19
vinte – 20
Example Q&A for 0–20
Use these short dialogs to practice aloud. Imagine a cashier or friend asking and you replying.
Q: Quantos apples?
Local natural phrasing: Quantas maçãs você quer?
A: Duas maçãs, por favor.
Q: Quantos anos você tem?
Natural: Quantos anos você tem?
A: Eu tenho vinte anos.
Q: Quanto custa?
Natural: Quanto custa essa blusa?
A: Custa dez reais.
Tens, twenties, hundreds, and combining numbers
Once you know 0–20, learn tens and hundreds, and how to combine them for numbers like 37 or 142.
trinta – 30
quarenta – 40
cinquenta – 50
sessenta – 60
setenta – 70
oitenta – 80
noventa – 90
cem – 100 (exactly 100)
cento – used for 101–199
duzentos – 200
trezentos – 300
quatrocentos – 400
quinhentos – 500
mil – 1000
How to combine tens and units
Put tens first, then the conjunction e, then the unit. Practice with Q&A patterns.
37 = trinta e sete
142 = cento e quarenta e dois
509 = quinhentos e nove
Example Q&A for combining numbers
Q: Qual é o número do ônibus?
Natural: Qual é o número do ônibus?
A: É o trinta e sete.
Q: Que sala é?
Natural: Em que sala é a aula?
A: É a sala cento e quarenta e dois.
Ordinal numbers: first, second, third
Ordinals are useful for floors, dates, sequences, and instructions. Note gender agreement with nouns.
primeiro / primeira – first
segundo / segunda – second
terceiro / terceira – third
quarto / quarta – fourth
Others follow similar patterns: quinto, sexto, sétimo, oitavo, nono, décimo
Example Q&A with ordinals
Q: Em que andar fica o apartamento?
Natural: Em que andar fica o apartamento?
A: Fica no segundo andar.
Q: Qual dia é a festa?
Natural: Em qual dia do mês é a festa?
A: É no dia primeiro de julho.
Common contexts and realistic dialogs
Below are practical scripts you will encounter: shopping, travel, phone numbers, schedules, and appointments. Practice both roles: asker and answerer.
Shopping
Q: Quanto custa isso?
Natural: Quanto custa essa camisa?
A: Custa quarenta e cinco reais.
Public transport
Q: A que horas sai o próximo ônibus?
Natural: A que horas sai o próximo ônibus para o centro?
A: Sai às dez e quinze.
Phone numbers
Q: Qual é o seu número?
Natural: Qual é o seu telefone?
A: É nove – oito – sete – seis – cinco – quatro – três – dois – um – zero.
Appointments
Q: Em que dia é a consulta?
Natural: Em que dia é a consulta médica?
A: É na segunda-feira, dia vinte e três.
Pronunciation tips
Numbers in Brazilian Portuguese have consistent stress patterns. Pay attention to nasal vowels and the e linking when combining tens and units.
Tip: When you say trinta e sete, link the e lightly so it sounds natural: trinta e sete -> trintae sete.
Tip: 100 is pronounced exactly as cem when alone, but cento in 101: cento e um.
Common mistakes and how to avoid them
Mistake: Using masculine forms like dois with feminine nouns. Match gender when counting objects: duas bolsas, dois carros.
Mistake: Forgetting the conjunction e between tens and units. Say trinta e dois, not trinta dois.
Mistake: Using cem for numbers above 100. Use cento e um for 101, not cem e um.
Practice: Create short Q&A drills that force correct gender and the e conjunction: Quantas cadeiras? Duas cadeiras. Qual número? Trinta e dois.
Practice routines: question-and-answer drills
Set up short sessions you can repeat daily. Each drill should be 5–10 minutes and focus on one context.
Drill 1: Prices – ask Quanto custa? and answer with amounts using reais and centavos: Custa vinte e cinco reais e cinquenta centavos.
Drill 2: Time – practice A que horas? with departures and appointments: Sai às nove e meia, chega às dez e quinze.
Drill 3: Quantities – use Quantos/Quantas? with objects and people: Quantos ingressos? Quatro ingressos.
Drill 4: Phone numbers and addresses – read numbers digit by digit and in groups: Rua Sete de Setembro, número cento e vinte e três.
Useful phrases with numbers
Quanto custa? – How much does it cost?
Quantos/Quantas? – How many?
Que horas? / A que horas? – What time?
Qual é o número? – What is the number?
Meu número é… – My number is…
Short realistic examples
Menu: Pizza média: trinta e nove reais. Refrigerante: sete reais.
Ticket desk: Só tenho passagens às treze e às dezesseis.
Bank form: Renda mensal: dois mil reais.
How to build quick memory aids
Use patterns rather than isolated words. Link a question with a typical answer, for example Quanto custa? Custa vinte reais. Repeating these pairs trains retrieval faster than isolated drilling.
Chunk numbers into groups: 1999 -> mil novecentos e noventa e nove and practice as a single spoken chunk.
Use phone-style digit practice for long numbers. Read slowly at first, then increase speed until you can say numbers fluidly.
Next steps after mastering beginner numbers
Once you are comfortable with basic Q&A patterns, move to listening practice with short audio dialogs, real menus, and street signs. Practice creating your own questions for friends or language partners and ask for spontaneous answers. Add percentages, money conversions, and dates as next challenges.
Conclusion
Learning Brazilian Portuguese numbers through questions and answers makes number vocabulary practical and memorable. Focus on common contexts—shopping, transport, phone numbers, and appointments—use gender agreement, practice the conjunction e, and do short daily Q&A drills. With realistic dialogs and repetition you will quickly understand and use numbers in everyday Brazilian Portuguese situations.
