Автор ответа: McProfessor

$3.5 - \frac{1}{3} = 3 \frac{5}{10} - \frac{1}{3} = 3 \frac{1}{2} - \frac{1}{3} = 3 \frac{3 - 2}{6} = 3 \frac{1}{6}$

$3.5 + 3 \frac{1}{6} = 3 \frac{5}{10} + 3 \frac{1}{6} = 3 \frac{1}{2} + 3 \frac{1}{6} = 6 \frac{4}{6} = 6 \frac{2}{3}$

Відповідь: 2 дині разом важать

$6 \frac{2}{3}$

Автор ответа: iramazurk

Ответ:

6 2/3 кг

Пошаговое объяснение:

1) 3,5 - 1/3 = 3 5/10 - 1/3 = 3 15/30 - 10/30 = 3 5/30 = 3 1/6 (кг) - весит вторая дыня

2) 3,5 + 3 1/6 = 3 5/10 + 3 1/6 = 3 15/30 + 3 5/30 = 6 20/30 = 6 2/3 (кг) - весят две дыни вместе

McProfessor: две дыни*

McProfessor: двери то побольше будут)))

iramazurk: ???

McProfessor: в вашем ответе

McProfessor: две двери весят, как две дыни

McProfessor: посмотрите

iramazurk: Ааа))) Прикол. Даже и не заметила. Сейчас исправлю. Спасибо))))))

McProfessor: Не за что =)
