Step-by-step explanation:

total number of student = 900

number of girls = 300

1) to find the number of boys

number of boys = total no. of students - no. of girls

= 900 - 300

= 600

2) to find the ratio of boys and girls

ratio of boys and girls = no. of boys : no. of girls

= 600 : 300

= 200

3) ratio of boys and total no. of students

= 600 : 900

= 200: 300

= 2:3

4) ratio of girls and total no. of students

= 300 : 900

= 1:3

5)ratio of girls and boys

= 300 : 600

= 1:2
