Question

Out of 60 students in a class 35 are boys. Find the ratio of (a) Boys to the total number of students (b) Girls to boys (c) Total number of students to girls​

Answer 1

Total no. of students= 60
Total no. of boys= 35
So, total no. of girls= Total no. of students - Total no. of boys
=60-35
=25 girls
Ratio of boys= 35/60
= 7/12
Ratio of girls= 25/60
= 5/12
So, Ratio of boys and girls=7:5❤️

Answer 2

Answer:

The answer to the following ratios are

a - 7: 12

b - 5: 7

c - 12: 5

Step-by-step explanation:

We have been mentioned here that there is a total of 60 students in the class out of which 35 are boys. Therefore the number of girls is found as below:

No. of girls = 60 - 35 = 25 girls.

Therefore following are the ratios:

a) Ratio of boys to the given total number of students = $\frac{35}{60}$

= $\frac{7}{12}$

= 7 : 12

b) Ratio of the total girls to boys = $\frac{25}{35}$

= $\frac{5}{7}$

= 5 : 7

c) Ratio of the total number of the students to girls = $\frac{60}{25}$

= $\frac{12}{5}$

= 12 : 5

Therefore these are the required ratios:

a - 7: 12

b - 5: 7

c - 12: 5
