Answer 2

Решим пример:

$\frac{19}{27} + \frac{14}{21} = \frac{19 \times 7}{27 \times 7} + \frac{14 \times 9}{21 \times 9} = \frac{133}{189} + \frac{126}{189} = \frac{133 + 126}{189} = \frac{259}{189} = \frac{37 \times 7}{27 \times 7} = \frac{37}{27} = \frac{1 \times 27 + 10}{27} = 1 \frac{10}{27}$
