Обратное к x - это 1/x. Разумеется, x будет больше. Сравни: 2 и 1/2, что в десятичной записи выглядит так: 2 и 0,5Почему обратно - 1/x?Мы можем представить x, как частное x и 1, т.е. x/1 . Тогда обратное будет 1/x

Tapecscript
Healthy Henry
Henry is a clerk in an office in town. He wants to
live to be a hundred, so health is very important to him.
He gets up at five o'clock in the morning and lifts
weights for thirty minutes. For breakfast he eats spinach and a row egg with
garlic. It tastes disgusting, but he thinks it's good for him. Then he runs for
an hour in a park, even if the weather is bad. He leaves for work at seven
o'clock. He never goes by bus or by train and he thinks that cars are extremely
dangerous. So he walks everywhere.
At the office he washes his hands ten times a day and
he wears gloves to pick up the telephone in case it's dirty. I le takes his
lunch to work with him. I Ie eats fifteen sunflower seeds and one onion.
After work he runs home to water the plants. 1 Ie has
hundreds of plants, because they provide oxygen. In the evening he sometimes
listens to the radio, but never watches television because it might damage his
eyesight.
On Monday he goes
to a deep breathing class and on Thursday he goes to a vegetarian cookery
class. He rarely goes to the cinema or to the theatre - there are far too many
germs. He goes to bed early. In summer he sleeps in a tent in the garden. At
the weekend he goes camping in the country, but he never sits in the sun. On
the first day of every month he goes to the doctor's, just to make sure that he
isn't ill. After all, he doesn't want to find himself in the hospital.
