determinati X, daca 15/X=5/2

Răspuns :

[tex] \frac{15}{x} = \frac{5}{2} \\ \\ x = \frac{15 \times 2}{5} = \frac{30}{5} = 6[/tex]

Raspuns:

[tex] \frac{15}{x} = \frac{5}{2} [/tex]

[tex] \frac{15 \times 2}{x} = 5[/tex]

[tex]15 \times 2 = 5x[/tex]

[tex]30 = 5x[/tex]

[tex]5x = 30[/tex]

[tex]x = \frac{30}{5} [/tex]

[tex]x = 6[/tex]
