1 pointsA class consist of 24 female students and 16 male students. The percentage of male student in the class is…
Benar
The percentage of male student in the class = \(\dfrac{16}{16 + 24} \times 100 \%\)
The percentage of male student in the class = \(\dfrac{16 \div \color{red} 8}{40 \div \color{red} 8} \times 100 \%\)
The percentage of male student in the class = \(\dfrac{2}{\cancel{5}} \times \cancelto{20}{100} \%\)
The percentage of male student in the class = \(40\%\)
Salah
The percentage of male student in the class = \(\dfrac{16}{16 + 24} \times 100 \%\)
The percentage of male student in the class = \(\dfrac{16 \div \color{red} 8}{40 \div \color{red} 8} \times 100 \%\)
The percentage of male student in the class = \(\dfrac{2}{\cancel{5}} \times \cancelto{20}{100} \%\)
The percentage of male student in the class = \(40\%\)
