There are 40 students in class six. \( 30 \% \) of them are girls \( \begin{array}{ll}\text { i) How many are girls ? } & \text { (ii) How many are boys? }\end{array} \)

To find out how many girls are in the class, simply calculate \( 30\% \) of \( 40 \) students. This is done by multiplying \( 40 \) by \( 0.30 \), which equals \( 12 \). So, there are \( 12 \) girls in class six! For the boys, we subtract the number of girls from the total number of students: \( 40 - 12 = 28 \). Thus, there are \( 28 \) boys in the class!
