How many decades in 6 months?

Answer 1

None. A decade is a period of ten years. You would have at least 120 months in one decade. 120 months = 1 decade 6 months = 6 x 1/120 decade = 0.05 decade

Answer 2

1 year = 12 months
1 decade = 10 years

6 decades = (6 x 10) years = (6 x 10 x 12) = 720 months.
