total number of students are 25 so givin boys number is 12 that way ratio of girls 13/25

7/3 girls to boys.

12 boys, 15 girls The composite numbers bit is irrelevant. b+g=27 g-b=3 add the equations b+g+g-b=27+3 2g=30 g=15

Ratios are good for comparing two quantities. Like in a classroom, the ratio of girls to boys, for example. Say the class has 40 students, and 22 of them are girls, so this is 22/40 = 55% of the class. But the ratio is comparing the girls to the boys, not the entire class. So if there are 55% girls, then 100% - 55% = 45% boys. Now the ratio can be made of 55 : 45 girl to boy ratio. This can be simplified to a 11:9 ratio.

boys 49% girls 51%
