Step-by-step explanation:
a. To find the percentage of the club that are boys, divide the number of boys by the total number of club members and multiply by 100. In this case, 55 boys out of 80 club members gives us a percentage of (55/80) * 100 = 68.75%.
b. To find the percentage of the club that are girls, subtract the percentage of boys from 100. In this case, 100 - 68.75 = 31.25%.
c. To express the percentage of boys in fraction form, divide the percentage by 100. In this case, 68.75% = 68.75/100 = 11/16.
d. To express the percentage of girls in fraction form, divide the percentage by 100. In this case, 31.25% = 31.25/100 = 5/16.
