Question 16

Question
PROBLEMAS 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].
