Question

Выполните действия 5) (17 5/14 - 29 4/21 ) (32,098 +5,902): (49 1/7- 30 10/21)
​

Answer 1

Пошаговое объяснение:

1).

$17 \frac{5(3)}{14(3)} - 29 \frac{4(2)}{21(2)} = 17 \frac{15}{42} - 29 \frac{8}{42} = - 12 \frac{7}{42} = - 12 \frac{1}{6}$

2).

$32.098 + 5.902 = 38$

3).

$49 \frac{1(3)}{7(3)} - 30 \frac{10(1)}{21(1)} = 49 \frac{3}{21} - 30 \frac{10}{21} = 18 \frac{14}{21} = 18 \frac{2}{3}$
