# Decimal

A decimal is a fractional number, represented as a base-10 numeral. Decimals are used in many different applications, including mathematics, finance, and engineering. Decimals are read and written using a decimal point, which separates the whole number part of the decimal from the fractional part. For example, the decimal 3.14 can be read as "three point one four".

Decimals are often used to represent numbers that are not easily expressible as whole numbers, such as pi (3.14159), or numbers with a large number of decimal places, such as Avogadro's number (6.02 x 10^23). Decimals can also be used to represent repeating decimal fractions, such as 1/3 (0.3333...) or 1/7 (0.142857...).

##### What is a decimal example?

A decimal example is a number that is expressed in decimal form. This can be done by using a decimal point, which divides the number into two parts: the integer part and the decimal part. The decimal part is always written after the decimal point, and represents a fraction of the whole number. For example, the number 12 can be written as 12.0, which means that it has an integer part of 12 and a decimal part of 0. Similarly, the number 12.5 can be written as 12.5, which means that it has an integer part of 12 and a decimal part of 0.5.

##### What are the 3 types of decimals?

Decimals are numbers that are used to represent fractions of whole numbers. There are three different types of decimals: terminating decimals, repeating decimals, and mixed decimals.

Terminating decimals are decimals that end after a certain number of digits. For example, the decimal 0.5 terminates after 1 digit. Repeating decimals are decimals that repeat a certain number after the decimal point. For example, the decimal 0.333 repeats the digit 3 after the decimal point. Mixed decimals are decimals that have both terminating and repeating digits. For example, the decimal 0.25 has a terminating 2 and a repeating 5. What is 10 as a decimal? Ten as a decimal is 10.0. How do you write decimals? To write a decimal, start by writing the number to the left of the decimal point. Then, write the decimal point. Finally, write the number to the right of the decimal point.

### How can I learn decimals easily?

There are a few key things to remember when learning decimals:

-Decimals are just a way of representing fractions (parts of a whole). So, if you understand fractions, you're already halfway there!

-The decimal point separates the whole number part of a decimal from the fractional part. So, in the decimal 0.5, the "0" is the whole number part and the "5" is the fractional part.

-Decimals can be added and subtracted just like whole numbers. However, when multiplying and dividing decimals, you need to be careful to line up the decimal points correctly.

Here are a few tips for practice:

-Start by writing out a number line from 0 to 1. Then, label the points on the number line with fractions (e.g., 1/2, 1/4, 3/4, etc.). Once you have a good understanding of fractions, you can start adding decimals to the number line.

-Practice adding and subtracting decimals with a partner. Make sure to line up the decimal points correctly!

-Finally, try some word problems that involve decimals. For example:

You have 3.4 yards of fabric. You want to cut it into 3 equal pieces. How long will each piece be?
