Question

-17*2/41
-24/71 : (-4)=

Answer 1

Ответ:

$-\dfrac{34}{41} \ ; \ \dfrac{6}{71} \ ;$

Пошаговое объяснение:

$-17 \cdot \dfrac{2}{41}=-\dfrac{17 \cdot 2}{41}=-\dfrac{(10+7) \cdot 2}{41}=-\dfrac{10 \cdot 2+7 \cdot 2}{41}=-\dfrac{20+14}{41}=-\dfrac{34}{41};$

$-\dfrac{24}{71}:(-4)=\dfrac{24}{71}:\dfrac{4}{1}=\dfrac{24}{71} \cdot \dfrac{1}{4}=\dfrac{24 \cdot 1}{71 \cdot 4}=\dfrac{6 \cdot 4}{71 \cdot 4}=\dfrac{6}{71};$
