1 determine the ratio of 1 decade to1 century in unit form
One decade is equal to 10 years, and one century is equal to 100 years.
To determine the ratio of one decade to one century in unit form, we can divide the number of years in one century by the number of years in one decade:
1 century / 1 decade = 100 years / 10 years = 10
Therefore, the ratio of one decade to one century in unit form is 1:10.
