Números racionais em matemática, apresenta de forma clara e prática o conceito e a aplicação dos números que podem ser expressos como frações. O aluno aprende a identificar, comparar e ordenar números racionais, entendendo sua representação em forma fracionária e decimal. São abordados tópicos como simplificação de frações, transformação de decimais em frações e vice-versa, além das operações fundamentais — adição, subtração, multiplicação e divisão — com números racionais. O curso também explica a diferença entre números racionais e irracionais, ajudando o estudante a compreender a estrutura do conjunto dos números reais. Por meio de exemplos e exercícios práticos, o aluno desenvolve raciocínio lógico e confiança para aplicar o conteúdo em situações do dia a dia e em provas escolares. Gis com Giz Matemática
