Question

1)3 1/5-(-4 1/7) 2)2/9-1/3

Answer 1

Ответ:

$1)7 \frac{12}{35}$

$2) \frac{1}{9}$

Пошаговое объяснение:

$1)3 \frac{1}{5} - ( - 4 \frac{1}{7} ) = 3 \frac{1}{5} + 4 \frac{1}{7} = (3 + 4) + ( \frac{1}{5} + \frac{1}{7} ) = 7 + ( \frac{1}{5} + \frac{1}{7} ) = 7 + \frac{12}{35} = 7 \frac{12}{35}$

$2) \frac{2}{9} - \frac{1}{3} = \frac{2 - 3}{9} = \frac{ - 1}{9} = \frac{1}{9}$
