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.
In Table 1, we are multiplying the decimal 0.2658 by powers of 10. Each time we multiply by a power of 10, the decimal point is moved one place to the right. In Table 2, we are dividing the whole number 265,800. by powers of 10.Each time we divide by a power of 10, the decimal point is moved one place to the left.hen multiplying a decimal by a whole number, placement of the decimal point is very important. Since there are two decimal digits in the factor $18.75, there must be two decimal digits in the product $3,750.00. This is because hundredths x whole number = hundredths.
