The ratio of girls to students at a middle school is 10 to 18. If there are 270 students at the school, how many are girls?

100
150
180
200

(I believe its 150, but I'm not sure. It'll be awesome if you can explain how to do this also)

Sagot :

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.
