GED Exam Flashcard Study System: GED Test Practice Questions and Review (2020) - Page 4 preview imageBasic MathAfractionis a number that is expressed as one integer written aboveanother integer, with a dividing line between them (). It represents thequotient of the two numbers “xdivided byy.” It can also be thought of asxout ofyequal parts.The top number of a fraction is called thenumerator, and it representsthe number of parts under consideration. The 1 inmeans that 1 partout of the whole is being considered in the calculation. The bottomnumber of a fraction is called thedenominator, and it represents the totalnumber of equal parts. The 4 inmeans that the whole consists of 4equal parts.A fraction cannot have a denominator of zero; this is referred to as“undefined.”

GED Exam Flashcard Study System: GED Test Practice Questions and Review (2020) - Page 6 preview imageBasic MathNumbers are the basic building blocks of mathematics. Specific featuresof numbers are identified by the following terms:Integers– The set of positive and negative numbers, including zero.Integers do not include fractions (), decimals (0.56), or mixed numbers ().Prime number– A whole number greater than 1 that has only two factors,itself and 1; that is, a number that can be divided evenly only by 1 anditself.Composite number– A whole number greater than 1 that has more thantwo different factors; in other words, any whole number that is not aprime number. For example: The composite number 8 has the factors of1, 2, 4, and 8.Even number– Any integer that can be divided by 2 without leaving aremainder. For example: 2, 4, 6, 8, and so on.Odd number– Any integer that cannot be divided evenly by 2. Forexample: 3, 5, 7, 9, and so on.

Proper fractions havevalues less than one while improper fractions have values greater thanone.Amixed numberis a number that contains both an integer and a fraction.Any improper fraction can be rewritten as a mixed number. Example:. Similarly, any mixed number can be rewritten as animproper fraction. Example:.

GED Exam Flashcard Study System: GED Test Practice Questions and Review (2020) - Page 10 preview imageBasic MathPercentages can be thought of as fractions that are based on a whole of100; that is, one whole is equal to 100%. The word percent meansperhundred. Fractions can be expressed as percentages by findingequivalent fractions with a denomination of 100. Example:;.To express a percentage as a fraction, divide the percentage number by100 and reduce the fraction to its simplest possible terms. Example:;.Converting decimals to percentages and percentages to decimals is assimple as moving the decimal point. To convert from a decimal to apercentage, move the decimal point two places to the right. To convertfrom a percentage to a decimal, move it two places to the left. Example:0.23 = 23%; 5.34 = 534%; 0.007 = 0.7%; 700% = 7.00; 86% = 0.86;0.15% = 0.0015.It may be helpful to remember that the percentage number will alwaysbe larger than the equivalent decimal number.

GED Exam Flashcard Study System: GED Test Practice Questions and Review (2020) - Page 12 preview imageBasic MathThegreatest common factor(GCF) is the largest number that is a factor oftwo or more numbers. For example, the factors of 15 are 1, 3, 5, and 15;the factors of 35 are 1, 5, 7, and 35. Therefore, the greatest commonfactor of 15 and 35 is 5.Theleast common multiple(LCM) is the smallest number that is amultiple of two or more numbers. For example, the multiples of 3include 3, 6, 9, 12, 15, etc.; the multiples of 5 include 5, 10, 15, 20, etc.Therefore, the least common multiple of 3 and 5 is 15.

GED Exam Flashcard Study System: GED Test Practice Questions and Review (2020) - Page 14 preview imageBasic MathFactorsare numbers that are multiplied together to obtain aproduct. Forexample, in the equation 2 × 3 = 6, the numbers 2 and 3 are factors. Aprime number has only two factors (1 and itself), but other numbers canhave many factors.Acommon factoris a number that divides exactly into two or more othernumbers. For example, the factors of 12 are 1, 2, 3, 4, 6, and 12, while thefactors of 15 are 1, 3, 5, and 15. The common factors of 12 and 15 are 1and 3.Aprime factoris also a prime number. Therefore, the prime factors of 12are 2 and 3. For 15, the prime factors are 3 and 5.

GED Exam Flashcard Study System: GED Test Practice Questions and Review (2020) - Page 16 preview imageBasic MathAnexponentis a superscript number placed next to another number atthe top right. It indicates how many times the base number is to bemultiplied by itself. Exponents provide a shorthand way to write whatwould be a longer mathematical expression. Example: a2= a × a; 24= 2 ×2 × 2 × 2. A number with an exponent of 2 is said to be “squared,” while anumber with an exponent of 3 is said to be “cubed.” The value of anumber raised to an exponent is called itspower. So, 84is read as “8 tothe 4th power,” or “8 raised to the power of 4.” Anegative exponentisthe same as the reciprocal of a positive exponent. Example: a-2= 1/a2.Parentheses are used to designate which operations should be done firstwhen there are multiple operations. Example: 4 – (2 + 1) = 1; theparentheses tell us that we must add 2 and 1, and then subtract the sumfrom 4, rather than subtracting 2 from 4 and then adding 1 (this wouldgive us an answer of 3).
