Ответ:

13\frac{23}{39}

Пошаговое объяснение:

2\frac{2}{15} * 1\frac{9}{16}

Переводим обе дроби в неправильные.

2\frac{2}{15} * 1\frac{9}{16} = \frac{32}{15} * \frac{25}{16}

Умножаем и сокращаем.

2\frac{2}{15} * 1\frac{9}{16} = \frac{32}{15} * \frac{25}{16} = \frac{32*25}{15*26} = \frac{16*5}{3*13} = \frac{530}{39}

Переводим в смешанную дробь.

2\frac{2}{15} * 1\frac{9}{16} = \frac{32}{15} * \frac{25}{16} = \frac{32*25}{15*26} = \frac{16*5}{3*13} = \frac{530}{39} = 13\frac{23}{39}

TEXT 1
At the Railway Station
It's common knowledge that nowadays people travel a lot. They travel on business and for pleasure, about the country and abroad. Those who wish to travel have at their disposal various means of transport: express trains and big ships, cars and jet airliners.
Although we all agree that the future belongs to the air transport, the railway is still one of the most popular means of communication. Of course, if people are short of time and have to travel a long distance they usually travel by air. But if they have time they prefer to go by train.
With a train you have speed, comfort and pleasure combined. From the comfortable corner seat of a carriage you have a splendid view of the country-side. If you are hungry you can have a meal in the dining-car and if the journey is long you can have a comfortable bed in a sleeper.
A big railway station is a very busy place. Let's imagine that we are in one of them.
There are a lot of platforms at which trains come in and go out. A train is standing at one of the platforms ready to leave. The porters are very busy carrying luggage to the train or pushing it on their trucks. On another platform the train has just come in. Some passengers are getting out, others are getting in. Those who haven't got their tickets in advance are waiting in queues at the booking-office. At the bookstalls people are choosing books, magazines and newspapers for the journey. There are a lot of notices in a big railway station. You may see ENTRANCE and EXIT. There is also a WAITING-ROOM where you can relax until it is time to board your train. If you are hungry or thirsty you'll go to the REFRESHMENT ROOM.
If you don't know the number of the platform from which your train leaves, look for the notices ARRIVALS and DEPARTURES. They will tell you the number of the platform.
When you arrive in a large town you may leave your heavy luggage at the station. In this case you will look for the CLOAK ROOM or LEFT LUGGAGE OFFICE.
You will also see the notice BOOKING OFFICE. This is where you buy your ticket. If you don't know the time or the platform your train leaves from you'll go to the INQUIRY OFFICE or the INFORMATION BUREAU.
