You can have either two or three leaps years in a decade and they alternate. So in the 20th century you had the following decades that had 3 leap years, the 1920s, 1940s, 1960 and 1980s as follows:
1920, 1924 and 1928.
1940, 1944 and 1948.
1960, 1964 and 1968.
1980, 1984 and 1988.
The answer to the question, as asked, is no one, since there were no number ones in, for example, the first decade of the fifteenth century!
Simple, you ask. And that answer is 10. Here's how it works: There are 10 years in a decade. There are 100 years in a century. 100 / 10 = 10
The decade in the 20th century with the most recorded Atlantic hurricanes was the 1950's with 106 named storms of which 70 storms attained hurricane intensity. However, the 1990's had the greatest number of named storms, 110 of which 63 became hurricanes. Also, it is worth noting that many storms in the earlier decades may have been missed due to the limited technology of the time.

A decade is 10 years. So, to find out the number of decades in a number of years, divide the number of years by 10. 50 / 10 = 5 5 Decades. 50 years = 5 decades.
A decade is equal to 10 years. Convert the decades to years. The idea is to subtract the specified number of years from 1826.
consolidation of banks in the later decades of the twentieth century (the number of commercial banks decreased by 45 percent between 1984 and 2002, from 14,496 to 7,966) tended to have a negative impact on rural lending
The twentieth prime number is 71
The math is trivial. The problem is knowing what the words mean."millennnium" = 1,000 years, mis-spelled"decade" = 10 years1,000/10 = 100 decades in one millennnium
A century is a period of 100 years. A decade is 10 years.* Historical periods are often defined as a century. However, because there was no 0th century, the century number is always 1 higher than the first two digits of the year number (e.g. 1950 is in the 20th century) except for years ending in 00, which are in the preceding century (1900 is in the 19th century with 1801-1899).
It is spelled twentieth. (from the number name twenty, 20)
I am a prime number. My only factors are 1 and 1999!
