Sunt elev in clasa 6 si trec in a-7a si am probleme la mate in legatura cu proportionalitatea si invers proportionalitatea.

{x;y;z} dp {2;23;10}

x/2=y/23=z/10

Cum fac????

le aduci la acelasi numitor. si o sa iti dea(zic la intamplare) 14x=45y=23z
zic eu. sper sa fie bine

You gave him what he asked for.

Quote:

{x;y;z} dp {2;23;10} (egalezi cu "K") => x=2k , y=23k , z=10k

x/2=y/23=z/10

=> 2k/2 = 23k/23=10k/10 , aduci la acelasi numitor si il afli pe "K" ,dupa care inlocuiesti sus in functie de ce rezultat are "k"
