Final answer:
To find the total number of students in Ms. Garcia's class, we can use the given ratio of boys to girls and the number of girls in the class. By setting up and solving an equation, we find that there are 20 students in total.
Step-by-step explanation:
To find the total number of students in Ms. Garcia's class, we can use the given ratio between boys and girls. The ratio is 2:3, which means for every 2 boys, there are 3 girls. We are given that there are 12 girls in the class. So, we can set up the equation:
2 / 3 = x / 12
Cross multiplying, we get:
2 * 12 = 3 * x
Simplifying:
24 = 3x
Dividing both sides by 3:
x = 8
Therefore, there are 8 boys in the class. To find the total number of students, we can add the number of boys and girls:
Total number of students = Number of boys + Number of girls = 8 + 12 = 20
