Решение:
$\frac{1}{2}$ = $\frac{1 * 24}{2 * 24}$ = $\frac{24}{48}$;
$\frac{2}{3}$ = $\frac{2 * 16}{3 * 16}$ = $\frac{32}{48}$;
$\frac{3}{4}$ = $\frac{3 * 12}{4 * 12}$ = $\frac{36}{48}$;
$\frac{5}{6}$ = $\frac{5 * 8}{6 * 8}$ = $\frac{40}{48}$;
$\frac{7}{8}$ = $\frac{7 * 6}{8 * 6}$ = $\frac{42}{48}$;
$\frac{11}{12}$ = $\frac{11 * 4}{12 * 4}$ = $\frac{44}{48}$;
$\frac{15}{16}$ = $\frac{15 * 3}{16 * 3}$ = $\frac{45}{48}$.
