Step-by-step explanation:

Total no of students are 500

No of boys=275

No of girls=500-275=225

Ratio of boys to total no of students=

No of boys÷total no of students=275÷500=11/20

Ratio of girls to boys=no of girls/no of boys=225/275=9/11

Ratio of girls to total no of students=no of girls/total no of students= 225/500=9/20
