$\frac{13}{19} + \frac{6}{19} = \frac{19}{19} = 1$
$\frac{8}{21} + \frac{3}{21} + \frac{5}{21} = \frac{11}{21} + \frac{5}{21} = \frac{16}{21}$
$\frac{36}{100} - \frac{14}{100} = \frac{22}{100}$
$\frac{48}{50} - \frac{14}{50} = \frac{34}{50}$
$\frac{3}{11} + \frac{7}{11} = \frac{10}{11}$
$\frac{18}{23} - \frac{9}{23} = \frac{9}{23}$
$\frac{36}{48} + \frac{7}{48} - \frac{1}{48} = \frac{43}{48} - \frac{1}{48} = \frac{42}{48}$
$\frac{35}{100} - \frac{9}{100} + \frac{1}{100} = \frac{26}{100} + \frac{1}{100} = \frac{27}{100}$
$\frac{17}{41} + \frac{14}{41} - \frac{8}{41} = \frac{31}{41} - \frac{8}{41} = \frac{23}{41}$
