Because you want girls to all pupils, you just put that number against one another, there fore 25:45; but you can simplify it further because you can divide both by 5, therefore 5:9
Answer:
5: 9
Step-by-step explanation:
The total number of students is
20+25 = 45
ratio is
boys : girls: total
20 : 25: 45
We can divide each of these by 5
20/5 : 25/5: 45/5
4 : 5 : 9
The ratio of girls to the total number is
5: 9
