Answers
Answer:
1:2
Step-by-step explanation:
number of girls in the class: 25
number of boys in the class: 25
therefore, total number of students in the class: 25+25 = 50
ratio of boys to total number of students = 25:50
i.e. = 1:2
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 boys + 25 girls = 50 students.
3. The ratio of two quantities x and y is calculated using the formula x/y. The ratio of x and y is represented as x:y.
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 of the total number of boys to the total number of students is 1:2.
