Answer 2

Given:

In a classroom, there are 25 boys and 25 girls.

To Find:

The ratio of the number of boys to the total number of students is?

Solution:

1. The total number of boys is 25 and the total number of girls is 25.

2. The total number of students in class is 25 + 25 = 50.

3. The ratio of two quantities a and b is calculated using the formula a/b. The ratio of a and b is represented as a:b.

4. The ratio of the total number of boys to the total number of students is,

=> (25) : (50),

=> 25/50, ( Simplify to standard form ),

=> 25/(25x2),

=> 1/2 = 1:2.

Therefore, the ratio is 1:2. Option A is the correct answer.
