Problema com frações? O macete que você precisa saber

Do you get stuck when adding fractions with different denominators, or do you already have the shortcut at your fingertips? 🧠✨ Our Question 13 presents the nightmare of many students: problems involving money, remainders, and fractions! Marcos spent 2/5 of his salary on rent and 1/4 on food, leaving him with R$ 1050.00. Where do most people slip up? Many try to equate the value in reais directly with the fractions spent, or get completely lost when trying to find the LCM (Least Common Multiple) to add expenses with different denominators (5 and 4). In this video, I, Professor Francisco de Assis (@prof.franciscodeassis), will guide you through a foolproof step-by-step process. We'll organize the expenses, find out which fraction represents what "remained," and use simple logic to find Marcos's total salary without needing complicated equations! 🎯 What you will learn in this lesson: Adding Different Fractions: The quick and correct way to add 2/5 and 1/4 without using the LCM to find the total expense. The Logic of the "Remainder": How to look at the fraction spent and instantly find out which fraction represents R$ 1050.00. Finding the Whole: The exact mathematical reasoning to find the full value (salary) from a piece (fraction). Grab your notebook, pause the video before my solution and see if you can arrive at the correct answer! 📢 JOIN OUR STUDY COMMUNITY: 👍 Did you like the step-by-step solution?
