5(a). A man shared his property among his children in the following percentages: Ann 5%, Afia 15%, Kojo 10%, Nuno 45%, Akosua 25%. Represent the information on a pie chart.
Model answer
Each share's angle = percentage × 360°/100. Ann = 5%×3.6 = 18°; Afia = 15%×3.6 = 54°; Kojo = 10%×3.6 = 36°; Nuno = 45%×3.6 = 162°; Akosua = 25%×3.6 = 90°. (Total = 360°). These angles are drawn as sectors of a circle to form the pie chart.
