Ответ:

Округление числа - это замена числа на его приближённое значение, записанное с меньшим количеством значащих цифр.

Пример:

117234 = 120000

113234 = 110000

115234 = 120000

Ответ:

Нужно цифру в разряде единиц заменить нулем, а если в записи числа есть цифры после запятой, то их следует отбросить. Если первая из отброшенных цифр 0, 1, 2, 3 или 4, то предыдущую цифру не изменяем.

In 1935 the Evening Teacher Training Institute was founded in Novosibirsk. There were only four departments in it. 109 students were trained there. In 1940 the Department for full-time students was opened. The first institute’s intake was 252 students. In 1968 the Institute began constructing a new building that was completed in 1975. The building was designed by the architect M.M.Pirogov. The campus includes educational buildings, the dining hall, the polyclinic, the sanatorium, the kindergarten, the workshops, the gymnasium, the stadium. Well-equipped laboratories and lecture-rooms with modern equipment: computers and a control system are at the students’ disposal. There is also a rich library with two reading-rooms, a beautiful conference hall, good hostels for students and postgraduates. There are also a lot of other facilities. Our University trains specialists for public education. There are about 10 thousand daytime students and 20 thousand of correspondence ones.
