Four score years, or eight decades.
A decade is 10 years therefore 8 decades is 80 years.
1 decade = 10 years. 10x8 = 80.
There are 100 years in each millennial. There are 10 decades in each 100 years. 100 x 8 = 800 X 10 = 8,000.
16 decades and 4 years.
80
Four score years, or eight decades.
8 times 10 years make 80 decades because 10 decades tines 8 decades will equal 80. (Hint:10 decades equals 1 year.)
A decade is 10 years therefore 8 decades is 80 years.
1 decade = 10 years. 10x8 = 80.
There are 100 years in each millennial. There are 10 decades in each 100 years. 100 x 8 = 800 X 10 = 8,000.
1 decade is 10 years which means 9 decades is 90 years. (10x9) 1 decade= 10 years (10x1) 2 decades= 20 years (10x2) 3 decades= 30 years (10x3) 4 decades= 40 years (10x4) 5 decades= 50 years (10x5) 6 decades= 60 years (10x6) 7 decades= 70 years (10x7) 8 decades= 80 years (10x8) 9 decades= 90 years (10x9) 10 decades= 100 years (10x10)
Decade = 10 years Century = 100 years so 8 decades mean 80 years which are smaller than 1 century.
There are 3.5 decades in 35 years
There are 5 decades in 50 years.
230 years = 23 decades
There are 20 years in two decades.
