$\frac {2}{3}$ + $\frac {3}{4}$ =	= $\frac {8+9}{3·4}$ = $\frac {17}{12}$ = $1\frac {5}{12}$
$\frac {1}{4}$ + $\frac {2}{3}$ =	= $\frac {3+8}{4·3}$ = $\frac {11}{12}$
$\frac {1}{2}$ + $\frac {3}{4}$ =	= $\frac {4+6}{2·4}$ = $\frac {5}{4}$ = $1\frac {1}{4}$
$\frac {1}{2}$ + $\frac {1}{3}$ =	= $\frac {3+2}{2·3}$ = $\frac {5}{6}$
$\frac {2}{3}$ + $\frac {1}{2}$ =	= $\frac {4+3}{3·2}$ = $\frac {7}{6}$ = $1\frac {1}{6}$
$\frac {1}{3}$ + $\frac {3}{4}$ =	= $\frac {4+9}{3·4}$ = $\frac {13}{12}$ = $1\frac {1}{12}$
$\frac {3}{4}$ + $\frac {1}{5}$ =	= $\frac {15+4}{4·5}$ = $\frac {19}{20}$
$\frac {2}{5}$ + $\frac {1}{3}$ =	= $\frac {6+5}{5·3}$ = $\frac {11}{15}$
$\frac {2}{5}$ + $\frac {1}{2}$ =	= $\frac {4+5}{5·2}$ = $\frac {9}{10}$
$\frac {1}{3}$ + $\frac {1}{5}$ =	= $\frac {5+3}{3·5}$ = $\frac {8}{15}$
$\frac {2}{3}$ + $\frac {3}{5}$ =	= $\frac {10+9}{3·5}$ = $\frac {19}{15}$ = $1\frac {4}{15}$
$\frac {3}{5}$ + $\frac {1}{3}$ =	= $\frac {9+5}{5·3}$ = $\frac {14}{15}$
$\frac {3}{5}$ – $\frac {1}{3}$ =	= $\frac {9–5}{5·3}$ = $\frac {4}{15}$
$\frac {2}{3}$ – $\frac {1}{4}$ =	= $\frac {8–3}{3·4}$ = $\frac {5}{12}$
$\frac {3}{4}$ – $\frac {2}{3}$ =	= $\frac {9–8}{4·3}$ = $\frac {1}{12}$
$\frac {3}{4}$ – $\frac {1}{2}$ =	= $\frac {6–4}{4·2}$ = $\frac {2}{8}$ = $\frac {1}{4}$
$\frac {1}{2}$ – $\frac {1}{3}$ =	= $\frac {3–2}{2·3}$ = $\frac {1}{6}$
$\frac {2}{3}$ – $\frac {1}{2}$ =	= $\frac {4–3}{3·2}$ = $\frac {1}{6}$
$\frac {3}{4}$ – $\frac {1}{3}$ =	= $\frac {9–4}{4·3}$ = $\frac {5}{12}$
$\frac {3}{4}$ – $\frac {1}{5}$ =	= $\frac {15–4}{4·5}$ = $\frac {11}{20}$
$\frac {2}{5}$ – $\frac {1}{3}$ =	= $\frac {6–5}{5·3}$ = $\frac {1}{15}$
$\frac {1}{2}$ – $\frac {2}{5}$ =	= $\frac {5–4}{2·5}$ = $\frac {1}{10}$
$\frac {1}{3}$ – $\frac {1}{5}$ =	= $\frac {5–3}{3·5}$ = $\frac {2}{15}$
$\frac {2}{3}$ – $\frac {3}{5}$ =	= $\frac {10–9}{3·5}$ = $\frac {1}{15}$
