In a class, there are 30 boys and 20 girls. What fraction of the students are boys?
Answer: C
Total number of students = Number of boys + Number of girls = 30 + 20 = 50.
Number of boys = 30.
Fraction of boys = \(\frac{\text{Number of boys}}{\text{Total students}} = \frac{30}{50}\).
Simplifying the fraction by dividing the numerator and denominator by 10 gives \(\frac{3}{5}\).
