Well, honey, if we're talking about decades, we're looking at groups of 10 years. So, if we're in the year 1285, we've got 1280-1289 to work with. That means we've got one decade in the year 1285. Math doesn't lie, darling.
77 decades and 1 year 77.1 x 10 = 771

30 years = 3 decades so 1 year = 1/30 or 0.0333... lots of 3 decades.
40, remainder 5
There are 60 minutes in one hour. Therefore, 1285 minutes is equal to 1285/60 = 21 remainder 25 or 21 hours 25 minutes. Expressed in decimal form, this is equal to 21.416 recurring (that is, 21.416666...) hours.
1285 plus 150 equals 2435, so add one more year for the year of 0 then it's 2436. There's your answer.
There are 12 decades in a 120 year period.

7 decades which is 70 years

A decade is 10 years. 2012 is one year. There are no decades in a single year. The years 2002 - 2012 represents a decade.
3 decades = 3 x 10 = 30 years
To calculate the years between 150 BC and 1285 AD, we need to consider that there is no year zero. From 150 BC to 1 BC is 149 years, and from 1 AD to 1285 AD is 1284 years. Adding these together gives a total of 149 + 1284 = 1433 years between 150 BC and 1285 AD.
