1/4 as a decimal is 0.25 of 100
1/100
A century has 100 years; so 25 years is one quarter of 100 years.
A quarter of a hundred (also 1/4 of a hundred) is 25, because when you multiply 1/4 by 100, you get 25. Another way to compute the answer is to know that multiplying by 1/4 is the same as dividing by 4. I.e. 100 ÷ 4 = 25
25% of 100 = 25
