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.
Write the decimal number above the number 1, as if you are going to divide it. For example, if the decimal is 0.625, write 0.625/1. Multiply both 0.625 and 1 by the multiple of 10 with the same amount of zeros as there are numbers after the decimal point.Since 0.625 has three numbers after the decimal point, multiply the numbers by 1,000, for example:implifying Fractions. The number 625/1,000 is a decimal fraction, meaning that you can reduce it to a smaller fraction. Do this by dividing both the top and bottom number by a common divisor, which is a number that both numbers can be evenly divided by.
