У перший день продали 1/5 значить 900/5 = 180 кг всій борошна, залишилося 900-180 = 720 кг  У другий день продали 2/5 залишку значить 720/5 * 2 = 288 кг  Залишилося продати: 900 (всього було) -180 (продали в перший день) -288 (продали в другий день) = 432 кг залишилося продати

My town – Armsheer
I live in a small city in the south of England. It’s called Armsheer. It has got great stadiums and is the best place to play football in the United Kingdom. There are lots of football schools where you can learn how to play football. I go to play football with my friends every weekend.
I love Armsheer because there are lots of other things to do as well as playing football. If you like sports with balls, you can go to play cricket, badminton or rugby. Cricket, football, rugby, tennis, table tennis, badminton, squash, canoeing and snooker were invented in Britain. Cricket is a popular summer sport in Britain. There are many cricket clubs in the town. Cricket players wear a certain uniform — white boots, a white T-shirt and white trousers. One cricket game takes a terribly long time. There are two teams of 11 players each and test matches between national teams can last up to 5 days. The spectators have to be very patient. The game is played on a pitch with a wicket at each end. The rules of the game have changed over the years. It is a game which is associated with long sunny summer afternoons, the smell of new-mown grass and the sound of leather ball beating the willow cricket bat. Cricket is more popular among men, but it is also played by women and girls.
