Special cases like centésimos (hundredths) and milésimos (thousandths) are also covered. The lesson encourages students to master these terms to improve their understanding and performance in mathematics.

Takeaways

• 😀 Correctly reading fractions is important to avoid common mistakes students make, such as misreading or mispronouncing them.
• 😀 Fractions with a denominator of 2 should be read as 'meios' (e.g., 5/2 = cinco meios).
• 😀 Fractions with a denominator of 3 should be read as 'terços' (e.g., 1/3 = um terço).
• 😀 Fractions with a denominator of 4 should be read as 'quartos' (e.g., 7/4 = sete quartos).
• 😀 The numerator stays the same when reading fractions; only the denominator changes the terminology.
• 😀 For fractions with a denominator of 5, the term 'quintos' is used (e.g., 2/5 = dois quintos).
• 😀 Fractions with denominators like 10, 100, and 1000 are special cases and have their own terminology: 'décimos', 'centésimos', 'milésimos', etc.
• 😀 When the denominator is greater than 10, the number is read normally and the suffix 'avos' is added (e.g., 11/10 = onze avos).
• 😀 For denominators of 100 and beyond, terms like 'centésimos' (100ths), 'milionésimos' (millionths), and similar are used.
• 😀 The presenter encourages students to learn the proper reading of fractions to excel in school exercises and mathematics.
• 😀 The video encourages viewers to subscribe to the channel and leave a 'like' to continue learning more about math.
