Я думаю, всі читали книгу або бачили фільм про Гаррі Поттера. У цьому творі є чарівні гроші — галлеони. Гаррі треба було купити 20 підручників для навчання. Кожнен підручник коштує 3 галлеони, а у Гаррі Поттера в гаманці всього 67 галлеонів. Чи вистачить Гаррі грошей на книги? У нас є три варіанти ділення. Використаємо їх! Отже: Варіант 1 : 67:20=3 галлеони (остача 7) Варіант 2 : 67:3=20 підручників (остача 7) Варіант 3 : 67: (20*3)=1раз (остача 7) Який варіант найлегший? Напишіть в коментарях 👇👇👇.
