Write numbers in words is lesson in elementary mathematics. To learn this easy technique, please follow this steps and solve worksheets.
Whole numbers
After we successfully learned how to name the decimal place of a number, we should learn how to write numbers in words.
Have you tried to spell out a number that has more than one digit? The precondition to learn this method is to know how count to ten. Let’s look at the number 179.
This number contains one hundred, seven tens and nine units. Keeping this in mind, we can write it as “a hundred seventy-nine“. We can also write it as “one hundred seventy-nine“, but if first digit in the number is 1 then we can use a single “a“ instead of “one“.
Hyphens are used between the smallest two digits in a number; between tens and units (ex. a hundred and twenty-seven), ten thousand and a thousand (six hundred and forty-seven thousand), ten million and a million (seven hundred and seventy-two million).
Decimal numbers in words
The technique to write bigger numbers in words is very similar to the technique of writing the whole numbers.
Let’s say that we have the number 8,592.594. In the last lesson we learned how to name decimal places. So, this number can be written as “Eight thousand five hundred ninety-two point five hundred ninety-four thousandths“.
To write down a larger number you need to form a group of digits on the left side of a decimal point.
Each group contains three digits – a hundred, ten and unit digit.
In our previous example, you can see that groups are separated with a comma. It is much easier to write the right side of a decimal point in words. In 0.594426 you have 2 groups with three digits. The first group is thousandths and the second is millionths.
For example, the number 2,347,568,592.594426 can be written as “Two billion, three hundred forty-seven million, five hundred sixty-eight thousand, five hundred ninety-two point five hundred ninety-four thousand, four hundred and twenty-six millionths”.
Fractions in words
If the number 2 is a denominator (the number under the fraction line) then the fraction is written as a “half/halves“. This means that $\frac{1}{2}$ will be written as “one-half“, $\frac{2}{3}$ as “two-halves“, $\frac{19}{2}$ as “nineteen-halves“, etc.
If the denominator is 3, then the fraction will be written as “third-thirds“. If denominator is 4, then there will be “fourth/fourths“. Lastly, if denominator is 27, then the fraction will be written as “twenty-sevenths“, etc.
Mixed numbers in words
Mixed number consists of a whole number and a fraction. Let’s say that we have number $ 7 \frac{4}{5}$. It will be written as “seven and four-fifths“. When you want to write the number in words, always remember to read it aloud.
