Vaca tot...vaca, dar sunt multe necunoscute in ecuatia aia! (IMG:style_emoticons/default/laugh.gif)
1-productia de iarba ce se obtine la hectar 2-ce suprafata are pasunea 3-temperatura ambianta (e stiut ca vaca mananca mai putin daca e canicula) 4-depinde si de vacar, daca e calificat sau daca e suparat pe sat |

Exact cate mananca de pe pasunea aia. Spre exemplu le pui pe alea 18 care mananca mai putin timp in care celorlalte 23 le dai reviste sa aibe ocupatie. Cand primele se satura, le aduci pe astea care intre timp au terminat de citit si le pui la pascut. Intre timp ti-ai format deja o parere despre comportamentul fiecarei vaci si te poti apuca de rezervat sala, biserica, formatie, aranjamente, etc. (IMG:http://weknowmemes.com/wp-content/uploads/2012/02/if-you-know-what-i-mean-420x250.png) |

Citeste despre regula de 3 compusa:
http://daniel-matei.blogspot.com/2008/02/r...-3-compusa.html Chiar ca-i de clasa a VI-a dar n-am timp sa ti-o rezolv acum. |

salutare ... sper sa fie corecta rezolvarea:
1. 18vaci consuma 1 pasune in 30zile ... deci 18vaci consuma 5/3 pasune in 50 zile 2. 23vaci consuma 1 pasune in 20zile ... deci 23vaci consuma 5/2 pasune in 50 zile scadem 18vaci din cele 23 ... respectiv cantitatea mancata de cele 18 vaci rezulta: 23-18 vaci ... consuma 5/2-5/3 din pasune ... in 50 zile adica 5 vaci consuma 5/6 din pasune ... in 50 zile deci ... o vaca consuma 1/6 din pasune in 50 zile => 6 vaci consuma pasunea in 50 zile. q.e.d. ( (IMG:style_emoticons/default/unsure.gif) sper ca e si corect ... ca mi-a luat vreo 30 minute) ... probabil ar trebui sa ma intorc putin spre clasa a-VI-a nu cred totusi ca se aplica regula de 3 compusa ... |

sigur textul problemei e corect ? adica 18 in 30 zile si 23 in 20 zile ?
pe ideea ca 18 in 30 => 9 in 60 zile si 23 in 20 => 7.(6) in 60 zile. nu trebuia sa fie acelasi numar acolo ? sau poate gandesc eu prost. |

idea e ca ai in buzunar 5 lei cand te verifici apoi ai 7 lei cand te reverifici . Cati lei ai in buzunar cand te verifici a treia oara stiind ca esti muritor de foame?
Problema nu are sens matematic . (Punct). |

18 vaci -----30 zile
cu 5 vaci in plus timpu in care se termina pasunea scade cu 10 zile, deci ca pasunea sa tina 50 de zile trebuie sa avem 8 vaci |

Asta e imposibila. Bine ca nu a intrebat cati litri de lapte dau vacile daca mananca atatea hectare.

Problema la aceasta problema e ca are datele incorecte. Adica daca 18 vaci mananca pasunea in 30 zile, atunci 23 n-au cum s-o manance in 20 decat daca mananca cantitati diferite pe zi.
