Final answer:
The ratio of girls to boys at Comanche Middle School is 4:2. By distributing the total number of students (183) across the ratio, we calculate that there are 120 girls at the school.
Step-by-step explanation:
To find out how many students are girls at Comanche Middle School, we need to use the given ratio of girls to boys, which is 4:2. This implies that for every 4 girls, there are 2 boys. To solve this, we first need to find the total number of parts that make up the whole. In this case, 4 parts (girls) + 2 parts (boys) = 6 parts in total. Now, to find out how many students each part represents, we divide the total number of students, 183, by the total number of parts:
183 ÷ 6 = 30.5
Since we can't have half a student, we know that our ratio should be adjusted accordingly. If we round down to 30, the total would be 30 * 6 = 180, missing 3 students to reach 183.
Rounding up to 31, the total would be 31 * 6 = 186, which is 3 students too many. The accurate representation would be taking the whole number part for the count of each ratio part. Thus:
Number of girls = 4 × 30 = 120
Therefore, there are 120 girls at Comanche Middle School.
