A decimal number is anything less than 1 that is not expressed by a fraction. Decimal points express the differentiation between the whole number and the less than whole number. If you are learning about decimal numbers and are having trouble reading them, say the whole number first, note where the decimal point is, and follow up with the numbers after the point to understand decimal numbers every time.
Steps
-
Say the number before the decimal point first. Decimal numbers are read left to right, just like normal numbers. Always start with the number that is to the left of the decimal place. This is the “whole” number. If there is no number before the decimal point, just say “zero.” [1] X Research source
- For example, if the number is 6.27, start by saying “six.”
Tip: If there is a zero in front of the decimal point, some people may skip saying “zero” all together and just go straight into saying “point” for the decimal point.
-
Read “and” as the decimal point. The period, or decimal point, in the number can simply be read as “and.” Say the decimal directly after the number that is in front of it, or else it can get confusing. The decimal point determines which numbers are whole numbers and which numbers are not. [2] X Research source
- For example, if the number is 6.27, you’d say “six and-”
- Some people may say “point” for the decimal point instead of “and,” especially outside of a math class.

Identify which place the last number is in after the decimal. It is important to be accurate when you are describing numbers in math. Determine which place the last number after the decimal is in by counting how many digits to the right of the decimal a number is. Then, add a 0 for each digit to the right. [3] X Research source Common decimal numbers end in the tenths, hundredths, or thousandths. [4] X Research source
- For example, In the number 6.2, 2 is in the tenths place.
- In the number 6.27, 7 is in the hundredths place.
- In the number 6.275, 5 is in the thousandths place.
-
Say the number after the decimal and add its numerical place to it. The number after the decimal has to be precise. Once you figure out what place the number is in, add that onto the number that you say after the decimal. This will make the decimal sound like a fraction, and it will be easier to work into equations in the future. [5] X Research source
- For example, if the number is 6.2, say “six and two tenths.”
- If the number is 6.27, say “six and twenty-seven hundredths.”
- If the number is 6.275, say “six and two hundred seventy-five thousandths.”
- If you are not doing a math equation, you can just read each number individually. For example, if your number is 6.27, say “six point two seven.”

Say the number before the decimal point and “dollars.” It is important to note that you are talking about money when you first read it out. As you begin reading from left to right, say the number that is before the decimal point followed by the type of money you are using. [6] X Research source
- For example, if the number is $4.50, start by saying “four dollars-”
-
Say “and” as the decimal point. When talking about money, the numbers after the decimal point are an addition to the number before the decimal point. When you are talking about money, say “and” when you see a decimal point like you would with a regular decimal number. [7] X Research source
- For example, if the number is $4.50, say “four dollars and-”
-
Read the number after the decimal point and say “cents.” The numbers after the decimal point describe the amount of money that doesn’t make up a full dollar. Read the number after the decimal point as a whole number on its own. Say “cents” after the word to distinguish it from the first number. [8] X Research source
- For example, if the number is $4.50, say “four dollars and fifty cents.”
- If the number is $39.89, say “thirty-nine dollars and eighty-nine cents.”
Tip: Cents can only go to the hundredths place, not above or below it. For example, the number $2.01 is two dollars and one cent.

-
QuestionWhich is greater, 12.30 or 12.6?Community Answer12.6. All you do is compare the first digit to the right of the decimal point. If those digits are the same, you'd compare the next digits to the right. For example, 12.75 is greater than 12.749. (You can think of 12.75 as 12.750.)
-
Questionhow do you say 0.07?Community AnswerThat is 7/100 or "seven hundredths". (Some people will say "seven one-hundredths".)
