Answer 1

Hint: In the question, there are two keywords century and fraction, by seeing century there should strike in our mind that century refers to 100 years and fraction is ratio of two whole numbers, so we simply have to find what is the fraction of 25 years in 100 years.

Complete step-by-step answer:
Given, 1 century and 25 years, we need to find the fraction.
As, in one century there are 100 years.
As, fraction is defined by $\dfrac{a}{b}$, where both a and b should be the whole number provided $b \ne 0$.
In this question we need to take the fraction of 25 and 100. Here, a will be 25 and b will be 100. Now, substitute both these values in $\dfrac{a}{b}$ and calculate the value.
So, it can be done as follows,
$\Rightarrow \dfrac{{25}}{{100}} = \dfrac{1}{4}$.
So, the fraction of 25 years of 1 century is $\dfrac{1}{4}$.
In one century there are 100 years.
Fraction is always a small part or small amount of any collection.

Note: In this question, first thing we need to know that a century is of any period of 100 years, period of 10 years is known as decade, the period of 25 years is called as quadricentennial and the period of 50 years is called as semi-centennial. Fraction is always a ratio of two whole numbers, so it will always be positive, if we take the ratio of two integers it is always a rational number, as integers can be negative.
