Clasificación de Fracciones y Operaciones Básicas

Las fracciones se clasifican según el resultado de su división. Cuando divides el numerador entre el denominador, puedes obtener tres tipos diferentes de resultados.

Una fracción pura es aquella que da como resultado un número decimal que termina exactamente, sin repetirse. Por ejemplo, 50÷3 = 16.666... donde los 6 se repiten infinitamente.

Las fracciones mixtas producen decimales que tienen una parte que se repite después de cierto punto. En el ejemplo 200÷27 = 7.407407..., la secuencia "407" se repite constantemente.

Una fracción exacta resulta en un decimal que termina completamente, como 150÷8 = 18.75. Aquí no hay números que se repitan infinitamente.

¡Dato curioso! Para sumar fracciones con diferentes denominadores, usas la fórmula: a/b + c/d = ad+bcad + bc/bd. ¡Es como encontrar un idioma común para que las fracciones se entiendan!

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
