Explicación paso a paso:

$\frac{3}{21}$ + $\frac{10}{21}$ + $\frac{23}{21}$ + $\frac{4}{21}$ = $\frac{3+10+23+4}{21}$ = $\frac{40}{21}$

$\frac{93}{120}$ - $\frac{83}{150}$ = $\frac{465}{600}$ - $\frac{332}{600}$ = $\frac{465-332}{600}$ = $\frac{133}{600}$   mcm=600

$\frac{17}{84} + \frac{3}{84} + \frac{5}{84} + \frac{11}{84} + \frac{6}{84} = \frac{17+3+5+11+6}{84} = \frac{42}{84} = \frac{1}{2}$

$\frac{7}{35} - \frac{1}{100} - \frac{11}{1000} = \frac{1400}{7000} - \frac{70}{7000} - \frac{77}{7000} = \frac{1400-70-77}{7000} = \frac{1253}{7000} =\frac{179}{1000}$  mcm=7000

$\frac{7}{5} + \frac{8}{15} + \frac{11}{60} = \frac{84+32+11}{60} = \frac{127}{60}$  mcm=60

$\frac{11}{12} - \frac{7}{12} - \frac{4}{12} = \frac{11-7-4}{12} =\frac{0}{12} =0$
