A decimal is a fraction written in a special form. Instead of writing 1/2, for example, you can express the fraction as the decimal 0.5, where the zero is in the ones place and the five is in the tenths place. Decimal comes from the Latin word decimus, meaning tenth, from the root word decem, or 10.
What is a decimal in math?
Decimals are a shorthand way to write fractions and mixed numbers with denominators that are powers of 10 , like 10,100,1000,10000, etc. If a number has a decimal point , then the first digit to the right of the decimal point indicates the number of tenths. For example, the decimal 0.3 is the same as the fraction 310 .
How do you understand decimals?
Commonly speaking we talk about decimals when numbers include a decimal point to represent a whole number plus a fraction of a whole number (tenths, hundredths, etc.). A decimal point is a point or dot used to separate the whole part of a number from the fractional part of a number.
What are the two types of decimal?
Types of Decimal Numbers
- Terminating Decimal Numbers. The terminating decimal numbers have a finite number of digits just after the decimal point.
- Non-Terminating Decimal Numbers.
- Recurring Decimal Numbers.
- Non-Recurring Decimal Numbers.
Why do we use decimals?
We use decimals every day while dealing with money, weight, length etc. Decimal numbers are used in situations where more precision is required than the whole numbers can provide. For example, when we calculate our weight on the weighing machine, we do not always find the weight equal to a whole number on the scale.

A finite decimal is one that stops, like 0.157 . An infinite repeating decimal is one that has a specified sequence of digits that repeat, Notice that in an infinite repeating decimal, the over-bar indicates the digits that repeat.
The first step in solving decimal arithmetic is being able to understand decimal numbers. Reading a decimal number is similar to reading a whole number except for a few minor differences. In a normal number the right most digit is ones place and the place next to it is tens place and so on the value of the position increases as you move left.
How can I explain decimals to kids?

How do we use decimals?
The decimal point is used to separate the whole number part from the fractional part; it is handy separator. Decimal numbers are used in situations which require more precision than whole numbers can provide. As we move to the right of the decimal point, each number place is divided by 10.
What is the Order of decimals?
The order from greatest to least is 2, 4, 5, 6, and 8. Because none of the numbers in the ones place are the same, it doesn’t matter what the decimal will be on these numbers- the order will remain the same. The order is 2.1, 4.8, 5.2, 6.9, 8.5.
