FRACCIONES o Q[blank_start]UEBRADOS[blank_end].
TÉRMINOS: N[blank_start]UMERADOR[blank_end] y D[blank_start]ENOMINADOR[blank_end].
Una FRACCIÓN indica una p[blank_start]artición[blank_end] en partes i[blank_start]guales[blank_end],
y equivale a una d[blank_start]ivisión[blank_end].
El TÉRMINO 1º se nombra con su C[blank_start]ARDINAL[blank_end].
El TÉRMINO 2º se nombra:
... Si es 2: m[blank_start]edio[blank_end]/s.
... Si es 3: t[blank_start]ercio[blank_end]/s.
... De 4 A 10: su o[blank_start]rdinal[blank_end].
... >10: su c[blank_start]ardinal[blank_end]+[blank_start]avo[blank_end]/s.

16PROBLEMAS con FRACCIONES ...
===========================
Una huerta tiene plantados 1/4 de tomates, 2/5 de pimientos y el resto, 280 m², de patatas.
¿Qué fracción hay plantada de patatas? ¿Cuál es la superficie total de la huerta?
[blank_start]1/4[blank_end] + [blank_start]2/5[blank_end] = [blank_start]13/20[blank_end]
[blank_start]1[blank_end] – [blank_start]13/20[blank_end] = [blank_start]7/20[blank_end] de patatas.
[blank_start]7/20[blank_end] = 280 => [blank_start]280[blank_end] : [blank_start]7[blank_end] x [blank_start]20[blank_end] = [blank_start]800[blank_end] m² superficie de la [blank_start]huerta[blank_end].

Un paso equivale a 3/5 de metro.
¿Qué distancia recorre con 1.000 pasos?
¿Cuántos pasos debe dar para recorrer una distancia de kilómetro y medio?
1.000 x [blank_start]3/5[blank_end] = [blank_start]600[blank_end] [blank_start]metros[blank_end].
kilómetro y medio => 1.000 + [blank_start]1/2[blank_end] x 1.000 = [blank_start]1.500[blank_end] [blank_start]metros[blank_end]
1.500 : [blank_start]3/5[blank_end] => 1.500 x [blank_start]5/3[blank_end] = [blank_start]2.500[blank_end] [blank_start]pasos[blank_end].
