Question

numerele a b c sunt direct pproportionale cu 2,3 si 4. aflati nr stiind ca cel mai mic este 12

Answer 1

  
[tex]\displaystyle\\ \frac{a}{2} = \frac{b}{3} =\frac{c}{4} \\\\ \text{2 este cel mai mic numitor.}\\ \Longrightarrow ~~~a\text{ este cel mai mic numar}\\ \Longrightarrow ~~~a=12 \\\\ \frac{12}{2} = \frac{b}{3} =\frac{c}{4} \\\\ b = \frac{12\times 3}{2} = 6\times 3 = 18\\\\ c = \frac{12\times 4}{2} = 6\times 4 = 24[/tex]
