Answer 1

Ответ:

1)

$4 \frac{1}{6} - 1 \frac{2}{15} = 4 \frac{5}{30} - 1 \frac{4}{30} = 3 \frac{1}{30}$

2)

$7 \frac{4}{21} + 2 \frac{1}{6} = 7 \frac{8}{42} + 2 \frac{7}{42} = 9 \frac{5}{14}$

3)

$2 \frac{7}{12} + 6 \frac{8}{9} = 2 \frac{21}{36} + 6 \frac{32}{36} = 8 \frac{53}{36} = 9 \frac{17}{36}$

4)

$3 \frac{5}{36} - 1 \frac{19}{45} = 3 \frac{25}{180} - 1 \frac{76}{180} = 2 \frac{205}{180} - 1 \frac{76}{180} = 1 \frac{129}{180} = \frac{309}{180} = \frac{103}{60}$

5)

$3 \frac{29}{36} - 3 \frac{1}{3} = 3 \frac{29}{36} - 3 \frac{12}{36} = \frac{17}{36}$

6)

$9 \frac{1}{6} - 3 \frac{14}{24} = 9\frac{4}{24} - 3 \frac{14}{24} = 8 \frac{28}{24} - 3 \frac{14}{24} = 5 \frac{14}{24} = 5 \frac{7}{12}$
