(i) How many students like to study Science

(ii) How many Students like to study Social Science

Science Answer: 19

Social Science Answer: 17

SOLUTION 1 :

Given :

Total number of students in the class = 44

(i) Out of 44 Students, $\frac{3}{7}$ of the students like to study Science .

Thus, the number of students who like to study Science = $\frac{3}{7}$ of 44

= $\frac{3}{7}$ x 44

= $\frac{(132)}{7}$

= 19

(ii) Out of 44 students , $\frac{3}{8}$ of the students like to study Social Science.

Thus, the number of students who like to study Social Science = $\frac{3}{8}$ of 44

= 3 x $\frac{44}{8}$

= $\frac{(132)}{8}$

=17

In a group of 59 students $\frac{4}{6}$ of the total number of students like to study Science , $\frac{1}{7}$ of the total number like to study socialscience.

Thus, the number of students who like to study Science = $\frac{4}{6}$ of 59

= $\frac{4}{6}$ x 59

= $\frac{(236)}{6}$

= 39

(ii) Out of 59 students , $\frac{1}{7}$ of the students like to study Social Science.

Thus, the number of students who like to study Social Science = $\frac{1}{7}$ of 59

= 1 x $\frac{59}{7}$

= $\frac{(59)}{7}$

In a group of 54 students $\frac{5}{8}$ of the total number of students like to study Science , $\frac{4}{9}$ of the total number like to study socialscience.
