In its simplest mathematical definition regarding data sets, the mean used is the arithmetic mean, also referred to as mathematical expectation, or average. Depending on the context, whether mathematical or statistical, what is meant by the "mean" changes. The word mean, which is a homonym for multiple other words in the English language, is similarly ambiguous even in the area of mathematics. Write the denominator in its ordinal number form.Related Statistics Calculator | Standard Deviation Calculator | Sample Size Calculator.Write the word form of the integer in the numerator.Generally, aside from exceptions, such as the word form of ½ being "one half" not "one second," the rules below can be used to write the word form of most fractions. The rules for writing fractions in word form are not as consistent as those for writing a decimal number, so instead of set rules, below are a few examples of the word forms of various fractions, as well as some general rules that apply to many fractions. Write the place value of the last digit after the hyphen.Hyphenate the last word in the word form of the number to the right of the decimal point.Write the word form of the number to the left of the decimal point first, then the word form of the number to the right.The table below shows the name of each place based on the place value of the number 1: For example, the decimal number 123.123 is written in word form as "One hundred twenty-three and one hundred twenty-three-thousandths." One key difference is the addition of the decimal point, which is written as "and." The numbers after the decimal point are written in the same way as any integer, except that the last digit in the number is hyphenated, and the place value of the digit is written after the hyphen. Decimal numbersĭecimal numbers are written in word form in a similar way as integers. Two hundred forty-nine billion, five hundred fifty-one million, six hundred seventy-two thousand, four hundred eighty-six. Attempt this before reading the solution below. Write out the word form of the three digits in each period, then add the respective period name after each, except for the ones period. We can separate each period with commas, as we would with numerals.
There are 4 periods in the above number: billions, millions, thousands, and ones. Use the place value chart to write the following number in word form. To write a given number in word form, identify the largest place value, write each number as we would in the ones place based on hundreds, tens, and ones, then write which period the digits fit into, whether it be millions, thousands, etc., but excluding the ones. This pattern continues for all the larger numbers (the smaller ones as well, if there are decimal places). The next period is the thousands, which also includes ones (thousand), tens (ten thousand), and hundreds (hundred thousands). The numbers described above fall within the ones period and involve ones, tens, and hundreds. Below is a figure showing the place values and periods through the billions. Writing larger numbers in word form requires an understanding of place value and periods. For example, 21 is written as twenty-one, 39 is written as thirty-nine, and so on. Numbers that include both tens and ones are hyphenated.
