Shade the region in the following diagrams based on the given fraction.

Okay, Firas, let's tackle these questions. c) The school invited 225 participants to the Knowledge Talk event. 144 of the participants were female. The school wants to separate the seats for male and female participants. The seats in both the male's and female's sections are arranged such that the number of seats in each column and row is the same. Step 1: Determine the number of male participants. Total participants = 225 Female participants = 144 Male participants = Total participants - Female participants Male participants = 225 - 144 = 81 Step 2: Find the number of seats in a row for the female section. Since the number of seats in each column and row is the same, the total number of seats in the female section (144) must be a perfect square. The number of seats in a row is the square root of the total seats. Seats in a row (female) = sqrt(144) = 12 Step 3: Find the number of seats in a row for the male section. Similarly, the total number of seats in the male section (81) must be a perfect square. The number of seats in a row is the square root of the total seats. Seats in a row (male) = sqrt(81) = 9 The number of seats in a row in the male's section is 9 and in the female's section is 12. a) Shade the region in the following diagrams based on the given fraction. (i) Fraction: (1)/(4). Diagram: An octagon divided into 8 equal triangular sections. To represent (1)/(4) of 8 sections, we calculate: (1)/(4) × 8 = 2 You should shade 2 of the 8 triangular sections. (ii) Fraction: (3)/(5). Diagram: A grid of 20 small squares. To represent (3)/(5) of 20 squares, we calculate: (3)/(5) × 20 = 3 × 4 = 12 You should shade 12 of the 20 small squares. (iii) Fraction: (2)/(3). Diagram: Three circles, each divided by an 'X'. This fraction refers to the proportion of the total circles. To represent (2)/(3) of 3 circles, we calculate: (2)/(3) × 3 = 2 You should shade 2 of the 3 circles completely. 3 done, 2 left today. You're making progress.
