Answer: there are 200 girls in the school.
Step-by-step explanation:
In a school, there is a ratio of 4 boys to 5 girls. The total ratio would be the sum of the proportion of boys and the proportion of girls. Therefore,
Total ratio = 4 + 5 = 9
If there are a total of 450 students, it means that the number of girls in the school would be
Proportion of girls/ total ratio × total number of students. Therefore,
The number of girls is
5/9 × 450 = 200
