PowerPoint Presentation. What is a decimal? A decimal is a number that shows tenths, hundredths, Thousandths, and so on, by using a decimal point.

38% = 0.38 in decimal form. Percent means ‘per 100’. So, 38% means 38 per 100 or simply 38/100. If you divide 38 by 100, you’ll get 0.38 (a decimal number).

“Two decimal places” is the same as “the nearest hundredth”. So, for example, if you are asked to round 3.264 to two decimal places it means the same as if your are asked to round 3.264 to the nearest hundredth. Some questions, like the example below, will ask you to “show your answer correct to two decimal places.”

A decimal number is defined as a number which is written in the decimal notation where each digit represents the different powers of 10. For instance, 20.456, 5. 006, 0.0001 are examples of decimal numbers.

Tips when teaching decimals

1. work with money – explain how the coins related to ones, tenths and hundredths.
2. show that the decimal point always separates the ones and the tenths.
3. ensure your child can read decimals.
4. explain and illustrate equivalent decimals.

Example: the numbers we use in everyday life are decimal numbers, because they are based on 10 digits (0,1,2,3,4,5,6,7,8 and 9). Example: 45.6 (forty-five point six) is a decimal number.

D) 0.000126. Hint:There are 60 seconds in a minute and 60 minutes in an hour. Therefore on multiplying all the values we get the number of seconds in an hour.

The decimal numeral system (also called the base-ten positional numeral system, and occasionally called denary /ˈdiːnəri/ or decanary) is the standard system for denoting integer and non-integer numbers. It is the extension to non-integer numbers of the Hindu–Arabic numeral system.

The number before the decimal point is called the whole part or integral part, Whereas the number after the decimal point is called the fractional part. Example : 43 is a whole part and 012 is a fractional part.

The concept of zero as a written digit in the decimal place value notation was developed in India, presumably as early as during the Gupta period (c. 5th century), with the oldest unambiguous evidence dating to the 7th century.

If there is no decimal point, it is understood to be after the last digit on the right and there is no place (zero place) accuracy. If a number has no place accuracy and there is a string of zeroes ending the number on the right, the significant digits are those digits to the left of the string of zeroes.

Hindu-Arabic numerals, set of 10 symbols—1, 2, 3, 4, 5, 6, 7, 8, 9, 0—that represent numbers in the decimal number system. They originated in India in the 6th or 7th century and were introduced to Europe through the writings of Middle Eastern mathematicians, especially al-Khwarizmi and al-Kindi, about the 12th century.

The first recorded zero appeared in Mesopotamia around 3 B.C. The Mayans invented it independently circa 4 A.D. It was later devised in India in the mid-fifth century, spread to Cambodia near the end of the seventh century, and into China and the Islamic countries at the end of the eighth.
