Step-by-step guide to solving Exercise 4 on Pages 35 and 36 in Math 4 Textbook
Problem Statement:
Answering the Questions:
a) Which century does the year 2000 belong to?
b) Which century does the year 2005 belong to?
c) The XXI century spans from which year to which year?
Solution Method:
Determining the century of a year:
- For a 3-digit year: Add 1 to the first digit.
- For a 4-digit year: Add 1 to the first two digits.
- Specifically, the year 2000 still belongs to the XX century because it is the last year of the 20th century (according to the Gregory calendar calculation: The 20th century starts from year 100 x 20 - 99 = 1901 and ends at the end of the year 2000, ensuring a century equals 100 years).
- Applying the Gregory calendar calculation:
+ The starting year of the century n = 100 x n - 99.
Answer:
a) The year 2000 belongs to the XX century (the 20th century)
b) The year 2005 belongs to the XXI century (the 21st century)
c) Extends from January 1, 2001, to December 31, 2100
