Razón, proporción y porcentaje

La razón, la proporción y el porcentaje son conceptos matemáticos fundamentales que permiten la comparación y relación entre diferentes cantidades. La razón es una forma de comparar dos cantidades de manera directa, como en el ejemplo donde se compara el número de hombres y mujeres en una fiesta.

Marine life, sea life or ocean life, is represented by the plants, animals and other organisms that live in the saltwater of the sea or ocean, or the brackish water of coastal estuaries.

At a fundamental level, marine life affects the nature of the planet. Marine organisms produce oxygen and sequester carbon.

Fish are limbless cold-blooded vertebrate animal with gills and fins living wholly in water.

Rays are the largest group of cartilaginous fishes, with well over 600 species in 26 families.

Rays look like bats in the water, and this is probably why they are called batoids. Rays use their pectoral fins to 'fly' through the water. Though a bony fish takes in water with its mouth, rays do not because they live at the bottom of the ocean.

Name a few of the most known species.

Si Juan se come 1 manzana por cada 2 peras al día, la proporción a la semana estaría dada por 1:2=7:14 pues una semana tiene 7 días.

Species in the shark subclass have skeletons made from cartilage, not bone, and have five to seven gill slits on each side of their heads (most other fish have only one gill slit on each side), which they use to filter oxygen from the water.

Enumerate a few of the most known species of sharks:

A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups.
The 3 main types of reef are: atoll, barrier reefs, fringing reefs.

Write down their characteristics as well as the importance of the reefs

En una fiesta hay 3 hombres por cada 5 mujeres la razón por medio del cual se puede expresar esta situación es: 3:5 ó 3 5

Cualquiera de las dos expresiones se puede leer como: 3 es a 5 ó 3 a 5

Es la comparación de dos cantidades

Seabirds are birds that are adapted to life within the marine environment. While seabirds vary greatly in lifestyle, behavior, and physiology, they often exhibit striking convergent evolution, as the same environmental problems and feeding niches have resulted in similar adaptations.


Name a few of bird species who live at sea or at the seaside:

Ejemplo
En un grupo de 30 estudiantes, 12 son varones. 12/30x100=40. Es decir que el 40% de los estudiantes son varones.
¿Qué es?

Es un número asociado a una razón, que representa una cantidad dada como una fracción en cien partes.
