Given:

Write all natural numbers from 1 to 25. What fraction of them are composite number.​

Solution:

Write all natural numbers from 1 to 25,

\[ \Rightarrow 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25\]

Write composite number between 1 and 25,

\[ \Rightarrow 4,6,8,9,10,12,14,15,16,18,20,21,22,24,25\]

Find the fraction,

\[ = \frac{15}{{25}}\]

\[ = \frac{3}{5}\]

Hence, the required fraction is \[\frac{3}{5}\].
