Answer 1

Ответ:

$\frac{4 {}^{3} }{13} + \frac{23 {}^{1} }{39} = \frac{12 + 23}{39} = \frac{35}{39}$

$\frac{16 {}^{1} }{45} + \frac{1 {}^{5} }{9} = \frac{16 + 5}{45} = \frac{21}{45} = \frac{7}{15}$

$\frac{29 {}^{1} }{42} + \frac{6 {}^{6} }{7} = \frac{29 + 36}{42} = \frac{65}{45} = 1 \frac{20}{42} = 1 \frac{10}{21}$

$\frac{7 {}^{1} }{32} + \frac{5 {}^{4} }{8} = \frac{7 + 20}{32} = \frac{27}{32}$
