At the time of answering this question (Saturday 14th December 2013), the year three decades ago was 1983.
From 2017, it was 1977.
1 decade is 10 years. The date is 10/27/11, so 10/27/01
Well, it depends on what year you are looking for, but 40 years ago from 2010 was the year 1970
The year 1612.
1915
1 decade = 10 years 10 decades = 100 years Today is 2010. 10 decades ago, it was 1910 .
From 2017, it was 1977.
1970 starting this year 2010
1970, starting this year (2010).
3 decades = 3 x 10 = 30 years
30 years = 3 decades so 1 year = 1/30 or 0.0333... lots of 3 decades.
30 years
From 2020, it was 2017 3 years ago.
The correct answer to your question is 2002
1958
1944 because a decade is ten years long and it is two decades ago so you subtract 20 from 1965 and you get 1944.
1 year = 12 months so 3 decades = 3*10 = 30 years = 30*12 = 360 months!
