Explanation:
- 64% of the class students are girls.
- 81.25% of these girls have chosen soccer as their favorite sport.
- 143 girls have chosen soccer as their favorite sport.
- Let’s find the total number of girls in the class:
- 81.25% of girls equals 143.
- Thus, total girls = 143 / 0.8125 = 176.
- The total number of students in the class is calculated as:
- 64% of total students = 176
- Total students = 176 / 0.64 = 275.
- Therefore, the total number of students: 275.
