Тест по математике Тема: Проценты Класс: 6 Тип вопросов: Открытый Количество вопросов: 3 Ответы даны после вопросов.

Вопросы

1. Сколько будет 25% от 320?
2. В шкафу 120 книг. 30% — художественная литература. Сколько книг художественной литературы?
3. Стоимость ноутбука была 8000 руб. На него сделали скидку 15%. Какая новая цена?

Ответы

1. 80

• Обоснование: 25% = 1/4. 320 ÷ 4 = 80.

2. 36

• Обоснование: 30% = 0.3 = 3/10. 120 × 3/10 = 360/10 = 36.

3. 6800 руб.

• Обоснование: 15% от 8000 = 0.15 × 8000 = 1200. Новая цена = 8000 − 1200 = 6800.
