The percentile rank of a particular score is defined as the percentage of the scores in a distribution which are at or below the particular score. It is possible to determine some percentile ranks directly from the frequency distribution table, provided that the percentile ranks are percentages that appear in the table.hen a score is identified by its percentile rank, the score is called a percentile. It is also possible to determine some percentiles directly from the frequency distribution table, provided that the percentiles are upper real limits of a category.
To divide a decimal by a whole number, divide as you would for whole numbers; and place a decimal point in the answer so that it lines up with the decimal point in the dividend.
First, make the whole number into a fraction. Make the number the denominator; the numerator is always 1. So now it looks like this: 3/ â¦ 4 + 1/8 Now convert the fractions so the denominators are the same. 4 goes into 8 2 times so we multiply the numerator by 2 as well.s a general rule, proper fractions cannot turn into whole numbers and only in limited cases are improper fractions able to. To turn an improper fraction into a mixed number, â¦ divide the denominator into the numerator. The result is the whole number. Put the remainder over the original denominator.
