Answer:
14.89%
Explanation:
Out of the total of 141 pupils, there are 21 Year 10 pupils in the tennis club. To find the percentage of Year 10 pupils in the club, you need to:
1. Divide the number of Year 10 pupils in the tennis club (21) by the total number of pupils (141).
21 ÷ 141 = 0.1489
2. Multiply the result by 100 to get the percentage.
0.1489 × 100 = 14.89%
Therefore, approximately 14.89% of the total pupils are Year 10 students in the tennis club.
