1) 12*3=36 (кг) - столько всего абрикосов было у продавца

2) 36-15=21 (кг) - столько абрикосов осталось

3) 21:3=7 (ящ.) - столько продал.

Ответ: 7 ящиков

 

 

4560 г = 4 кг 560 г

5870 кг = 58 ц 70 кг

2730 ц = 273 т 

2480 кг = 2 т 480 кг

8273 мм2 = 82 см2 73 мм2

1486 см2 = 14 дм2 86 см2

760 мин = 12 ч 40 мин
