Question

In a class of 40 students 1/5 of the total number of students like to study English 2/5 of the total number like to study Mathematics and the remaining students like to study Science. 1) How many students like to study English 2) How many students like to study Mathematics 3) what fraction of the total number of students like to study Science


​

Answer 1

The three answers are answered below:

Step-by-step explanation:

1) The 1/5 of 40 would 8, as

$\frac{1}{5}$ x 40 = 1 x 8 = 8

Hence, 8 students like to study English.

2) Just like the above process,

The 2/5 of 40 would 16, as

$\frac{2}{5}$ x 40 = 2 x 8 = 16

Hence, 16 stuents like to study Mathematics.

3) To find the total number of students who like Science, there are two options, either you can find the fraction of the number of students who like to study Science, which would be,

Total - number of students who like to study Science - number of students who like to study Science

1 - 1/5 - 2/5, which would be 2/5, and the answer would be 16 students.

Or you can directly use this formula,

Total - number of students who like to study Science - number of students who like to study Science

and calculate,

40 - 8 - 16 = 40 - 24 = 16 students
