Answer 1

$\frac{5}{21} + \frac{10}{21}+ \frac{23}{21} + \frac{4}{21} = \frac{5+10+23+4}{21} = \frac{42}{21} = 2$

$\frac{5}{24} + \frac{7}{24} + \frac{11}{24} + \frac{13}{24} + \frac{17}{24} = \frac{5+7+11+13+17}{24} = \frac{53}{24}$

$\frac{41}{79} + \frac{37}{79} + \frac{25}{79} +\frac{71}{79}+ \frac{63}{79} = \frac{41+37+25+71+63}{79} = \frac{237}{79} = 3$

$\frac{3}{17} +\frac{8}{17} +\frac{11}{17} +\frac{23}{17} = \frac{3+8+11+23}{17}= \frac{45}{17}$

$\frac{1}{6} +\frac{7}{6} + \frac{11}{6} + \frac{13}{6} = \frac{1+7+11+13}{6} = \frac{32}{6} = \frac{16}{3}$

$\frac{11}{14} -\frac{5}{14} = \frac{11-5}{14} = \frac{6}{14} = \frac{3}{7}$

$\frac{46}{51} -\frac{20}{51} - \frac{9}{51} = \frac{46-20-9}{51} = \frac{17}{51} = \frac{1}{3}$

$\frac{19}{21} -\frac{2}{21} - \frac{4}{21} - \frac{3}{21} = \frac{19-2-4-3}{21} = \frac{10}{21}$

$\frac{23}{25} -\frac{11}{25} - \frac{7}{25} = \frac{23-11-7}{25} = \frac{5}{25} = \frac{1}{5}$


 \frac{1}{42}  - \frac{7}{42} = \frac{19-12}{42} = \frac{7}{42} =  \frac{1}{6}
