This document provides an overview of fractions and decimals in Spanish for 7th grade students. It begins with introductory concepts about fractions and how they represent the division of a whole into equal parts. It then discusses reading fractions using cardinal and partitive numbers. Several examples of fractions and exercises are provided. Additional sections cover fraction-decimal conversions, inequality concepts on number lines, and worked problems for students to practice solving inequalities.

5. Las fracciones son las formas en las
que pueden clasificarse la división de
un número en partes iguales.
Fracción

Por ejemplo: dividir un pastel en 8 partes iguales,
cuando tomas una, estás tomando una fracción
de ese pastel.

6. You can give a brief description of the topic you
want to talk about here. For example, if you want to
talk about Mercury, you can say that it’s the smallest
planet in the entire Solar System
INTRODUCTION

7. El numerador de un
fraccionario se lee
con los números
cardinales.
El denominador se lee con los
números partitivos.
2 = medios
3 = tercios
4 = cuartos
5 = quintos
6 = sextos
7 = séptimos
8 = octavos
9 = novenos
10 = décimos
A partir del 11, el número se lee
como un número cardinal,
terminado en “avos''.
11 = onceavos
12 = doceavos
Y así sucesivamente.

METHODS TO SOLVE INEQUALITIES

13. If we consider the true inequality
4 < 8
6 < 10
2 < 6
8 < 16
2 < 4
Adding 2 to both sides The inequality sign holds true
Subtracting 2 from both
sides
Multiplying both sides by +2
The inequality sign holds true
The inequality sign holds true
Dividing both sides by +2 The inequality sign holds true
