¿Qué es la Regla de 3?

La regla de 3 es como una fórmula mágica que te ayuda a encontrar un número desconocido cuando ya tienes otros tres números relacionados. Imagínate que es como completar un rompecabezas donde te falta una pieza.

Esta herramienta funciona porque los números forman una proporción, que significa que tienen una relación especial entre ellos. Es como cuando comparas precios en el supermercado: si 2 chocolates cuestan $1000, ¿cuánto costarán 6 chocolates?

Para resolverla, solo necesitas seguir estos pasos simples: multiplicas los dos números que están en diagonal (como una X) y luego divides entre el número que queda. En el ejemplo del ejercicio: 4 × 9 ÷ 3 = 12.

💡 Tip clave: Siempre verifica tu respuesta preguntándote si tiene sentido. Si compras más chocolates, deberías pagar más dinero, ¿verdad?

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.
