Вопрос школьника по предмету Математика
В романе Гюго Антон прочитал что старинное судно делает четыре морских лье в час (1 морское лье равно 5,556 км). Сколько километров проходит судно за 10 минут? Ответ округлите до десятых
Ответ учителя по предмету Математика
1) 10 мин= 1/6 часть от 1 часа
2) 4*1/6= 4/6 (лье) — судно пройдет за 10 мин
3) 4/6*5,556=4/6*5 целых 556/1000=4/6*5556/1000=926/250=3 целых 176/250

Alex: That’s a difficult question. I haven’t made
up my mind what I want to do when I leave
school. I think I need a break to do something different. That’s why I choose a gap year. I want to travel, earn money, and get skills and
life experience.
Liza: Possibly, but do you ignore the idea of applying to college?
