Title: How to Write in Decimals: 10 English Words You Need to Know
H2: Introduction
Writing in decimals is an important skill to have in many fields, including science, finance, and mathematics. In this article, we’ll cover the ten English words you should know to effectively write in decimals.
H2: Integer
An integer is a whole number without any decimal or fractional component. When writing in decimals, a number may have a whole number component, which is called the integer portion. For example, in the number 3.14, the integer portion is 3.
H2: Decimal Point
A decimal point is a punctuation mark used to separate the integer from the fractional portion of a number. In English, the decimal point is represented by a period. For example, in the number 3.14, the decimal point is located between the 3 and the 1.
H2: Fraction
A fraction is a numerical quantity that represents a part of a whole. In decimals, fractional values are represented after the decimal point. For example, in the number 0.5, the fraction is 0.5, which represents half of a whole.
H2: Zero
Zero is a numeric value that represents the absence of any quantity. In decimals, zero is used as a placeholder when a number has no value in a particular decimal place. For example, in the number 0.05, the zero is used as a placeholder between the decimal point and the 5.
H2: Decimal System
The decimal system is a base-ten numerical system that uses the digits 0 to 9 to represent values. Each digit in a number represents a different power of ten. In decimals, the decimal point signifies the separation of values in different power positions.
H2: Significant Digits
Significant digits in a number are digits that contribute to the overall value of the number. In decimals, significant digits are all the digits that appear before the first non-zero digit or after the last non-zero digit. For example, in the number 0.00314, there are three significant digits.
H2: Rounding
Rounding is the process of simplifying a number to a certain number of significant digits. In decimals, rounding is necessary when a number has too many significant digits to be practical or precise. To round a number, identify the digit to be rounded and look at the adjacent digit to determine whether to increase or keep the digit the same.
H2: Scientific Notation
Scientific notation is a way to express large or small numbers in a concise manner. In scientific notation, a number is expressed as a power of 10 multiplied by a number between 1 and 10. For example, the number 5,000,000 can be expressed as 5 x 10^6.
H2: Conclusion
Writing in decimals requires understanding of several key English words, including integer, decimal point, fraction, zero, decimal system, significant digits, rounding, and scientific notation. Knowing these words and their meanings will allow you to communicate effectively when writing in decimals in various fields.
