Ответ:
1 1/9
Пошаговое объяснение:
(1/15 + 7/45) : 1/5 =1 1/9
1) 1/15 + 7/45 = 3/45 + 7/45 = 10/45 = 2/9
2) 2/9 : 1/5 = 2/9 * 5/1 = 10/9 = 1 1/9
[tex]( \frac{1}{15} + \frac{7}{45} ) \div \frac{1}{5} = \frac{1}{15} \div \frac{1}{5} + \frac{7}{45} \div \frac{1}{5} = \frac{5}{15} + \frac{7 \times 5}{45} = \\ = \frac{1}{3} + \frac{7}{9} = \frac{3}{9} + \frac{7}{9} = \frac{10}{9} = 1 \frac{1}{9} [/tex]
