Explicație pas cu pas:
[tex] \frac{x}{4} = \frac{13}{2} = > x = \frac{4 \times13}{2} = \frac{52}{2} = 26[/tex]
[tex] \frac{9}{x} = \frac{3}{10 } = > x = \frac{9 \times 10}{3} = \frac{90}{3} = 30[/tex]
[tex] \frac{7}{8} = \frac{x}{16} = > x = \frac{7 \times 16}{8} = \frac{112}{8} = 14[/tex]
[tex] \frac{x}{15} = \frac{4}{5} = > \frac{15 \times 4}{5} = \frac{60}{2} = 12[/tex]
[tex] \frac{4}{11} = \frac{8}{x} = > x = \frac{11 \times 8}{4} = \frac{88}{4} = 22[/tex]
[tex] \frac{24}{ x} = \frac{6}{5} = > x = \frac{24 \times 5}{6} = \frac{120}{6} = 20[/tex]
