55% of the people at the fun fair were children, and 45% were adults.
Solución
Total number of people = 300
Number of children = 165
Number of adults = 300 − 165 = 135
(a) To find the percentage of children:
Percentage of children = (Number of children / Total people) × 100
= (165 / 300) × 100
= 0.55 × 100
= 55%
(b) To find the percentage of adults:
Percentage of adults = (Number of adults / Total people) × 100
= (135 / 300) × 100
= 0.45 × 100
= 45%
Thus, 55% of the people at the fun fair were children and 45% were adults.

To find the percentage of children at the fun fair, divide the number of children (165) by the total number of people (300) and multiply by 100. So, (165/300) * 100 = 55%. This means that 55% of the people at the fun fair were children! For adults, there were 300 - 165 = 135 adults. To find the percentage of adults, you divide the number of adults by the total number of people and multiply by 100. So, (135/300) * 100 = 45%. Therefore, 45% of the people at the fun fair were adults!
