A decade equals 10 years, so to convert 4 billion years to decades, simply divide by 10.
4,000,000,000 years / (10 years/ decade) = 400,000,000 decades.
So 4 billion years is 400 million decades
4 decades, 4 years
Earth is about 4.5 to 4.6 billion years old. The universe is about 13.7 billion years old.
6 decades=60 years so no its not
Oh, what a lovely question! Let's see here. 3 centuries is 300 years, 7 decades is 70 years, and 4 years is, well, 4 years. If we add them all together, we get a total of 374 years. Isn't that just a happy little sum?
If the year is 1969, four decades later would be 2009. This is because a decade consists of 10 years, so four decades would be 40 years. Adding 40 years to 1969 gives us the year 2009.
16 decades and 4 years.
4 decades, 4 years
About 4 and a half billion years.
It is 4 billion years
Over the last 4 billion years.
As we know that a decade is 10 years So, 1 decade = 10 years 4 decades = 4 x 1= = 40 years Thus, 4 decades is equal to 40 years.
No. Earth itself is "only" about 4.6 billion years old. The first life may have emerged about 4 billion years ago.
in one decade there are 10 years, so if you times 10 by 4 you will get 40 so there are 40 years in 4 decades.
A decade is ten years. So, four decades is forty years.
100 years
Approximately 4 billion years.
Around 4-5 billion years.
