(2) 16 Students

(3) The fraction of Students who like to study Mathematics is equal to No of Students who like to study Science. Therefore, The fraction of Students who like to study = 2/5

Step-by-step explanation:

$Total \: \: Students \: \: in \: \: Class : \large\bf40 \\ \\ Total \: \: No \: \: of \: \: Students \: \: who \\ like \: \: to \: \: study \: \: \bf English : \\ ➜ \: \: \frac{1}{5} \times 40 = \large\bf 8 \: \: Students \\ \\ Total \: \: No \: \: of \: \: Students \: \: who \\ like \: \: to \: \: study \: \: \bf Mathematics : \\ ➜ \: \: \frac{2}{5} \times 40 = \large\bf16 \: \: Students \\ \\ Total \: \: No \: \: of \: \: Students \: \: who \\ like \: \: to \: \: study \: \: \bf Science : \\ ➜ \: \: 40 - (8 + 16) \\ = 40 - 24 \\ = \large\bf16 \: \: Students$
