Answer :
The ratio is 10 to 18, therefore 10 * nr of students = 18 * nr of girls.
So the number of girls = nr of students * 10 / 18 which is indeed 150.
Answer:
The answer is 150.
Step-by-step explanation:
Let the number of girls be = x
Total students in the school = 270
The ratio of girls to students at a middle school is 10 to 18.
Now, we can write the relation as:
[tex]\frac{10}{18}= \frac{x}{270}[/tex]
[tex]18x=2700[/tex]
x = 150
So, the total girls are = 150.
