rational number is a number that can be written as a ratio of two integers. The decimal of a rational number will either repeat or terminate. There is a way to tell in advance whether a rational number’s decimal representation will repeat or terminate. When trying to find a pattern in the relationship between rational numbers and their decimals‚ it is best to start with a list. A random list of rational numbers and their decimal values was made in order to find a pattern. The list included ½‚ 5/6‚ 44/10

Chemical Formulas Review: Nomenclature and Formula Writing Naming Simple Compounds There are four naming systems you should familiarize yourself with to succeed on the SAT II Chemistry exam. The trick is recognizing which naming system to use. Here are the guidelines: * If the compound starts with H‚ it is an acid. Use the naming acids rules. * If the compound starts with C and contains quite a few H’s and perhaps some O’s‚ it is organic. Use the naming organic compounds rules. *

and remember than the precise number. In MyFinanceLab most of our answers are rounded decimal numbers. A decimal number has three parts: The whole number part‚ the decimal point and the decimal part. For example: [pic] So‚ in order to round a decimal number we basically round the decimal part of it. These are the two basic steps for rounding decimals to a place value to the right of the decimal point Step 1: Locate the digit to the right of the given place value. Step 2: If this

The decimal numeral system (also called base ten or occasionally denary) has ten as its base. It is the numerical base most widely used by modern civilizations. Modern computer hardware and software systems commonly use a binary representation internally (although many early computers‚ such as the ENIAC or the IBM 650‚ used decimal representation internally). For external use by computer specialists‚ this binary representation is sometimes presented in the related octal or hexadecimal systems.
