The percentile rank for 10 will be 10th.
<h3>What is percentile rank?</h3>
The percentile rank of a particular score in statistics refers to the percentage of scores in the frequency distribution that are smaller than that score.
Percentile rank = [(Number of values below x) + 0.5]/ total number of values * 100
For 10,
Percentile rank = {[0 + 0.5]/5} x 100 = 10th
For 15,
Percentile rank = ([1 + 0.5]/5) x 100 = 30st
For 19,
Percentile rank = [2 + 0.5]/5 x 100 = 50th
For 23,
Percentile rank = [3 + 0.5]/5 x 100 = 70th
For 30,
Percentile rank = [4 + 0.5]/ 5 x 100 = 90th
The percentile rank for 10 will be 10th.

53). 100 servings / 20 people = (100/20) (svngs/ppl)
= 5 servings per person.
Each person gets 1/20 = 5% = 0.05 of the pan.
54). 100 servings / 40 people = (100/40) (svngs/ppl)
= 2.5 servings per person.
Each person gets 1/40 = 2.5% = 0.025 of the pan.
55). 100 servings / 30 people = (100/30) (svngs/ppl)
= (3 and 1/3) servings per person.
Each person gets 1/30 = (3 and 1/3) % = 0.0333... of the pan.
