Questions & Answers (A+ Guide Solution)
Integer - answer-set of whole positive and negative numbers includes zero.
Does not include fractions, decimals, or mixed numbers
Prime number - answer-whole number greater than one, only has two factors
(itself and 1)
Composite number - answer-whole number greater than one, has more than
two factors
Scientific notation - answer-way of writing larger numbers in a shorter form 𝑎 ×
10^𝑛, a is greater than or equal to 1 but less than 10
Fraction - answer-number expressed as one integer (numerator) written above
another integer (denominator) with dividing line b/t them, x/y. Represents
quotient of 2 numbers, x divided by y
Equivalent fraction - answer-can manipulate fractions by multiplying
numerator and denominator by same number, have a fraction that is
technically equal in value, can also divide numerator and denominator by same
number to create fraction that is equal in value
,Common denominator - answer-Manipulate fraction to have two or more
fractions with same denominator, should be LCM of original denominators
Adding/Subtracting Fractions - answer-Need to have common denominator
first, then can add/subtract numerators
Multiplying fractions - answer-Multiply across (numerator by numerator and
denominator by denominator) to obtain new values
Dividing fractions - answer-Flip numerator and denominator of 2nd fraction
and then proceed as if multiplying
Improper fraction - answer-Numerator is larger than denominator, can be
written as mixed number
Mixed number - answer-number that contains integer and fraction, can be
written as improper fraction
Percentages - answer-fractions based off of whole of 100, one whole equals
100%
Converting decimals to percentages - answer-move decimal point
Ways to present percentage problem - answer-1. find what percentage of
some number another number is
, 2. find what number is some percentage of a given number
3. find what number another number is a given percentage of
Would use
% = Part/Whole and Whole = Part/Percentage
to figure out all of these problems
Ratio - answer-comparison of 2 quantities in particular order
Proportion - answer-relationship b/t two quantities that dictates how one
changes when the other changes
Pythagorean theorem - answer-a^2 + b^2 = c^2, states relationship between
legs and hypotenuse of a right triangle
Triangle Inequality Theorem - answer-sum of the measures of any two sides of
a triangle is always greater than the measure of the third side
Sum of interior angles - answer-for triangle is always 180 degrees, cannot have
more than one angle with measure greater than or equal to 90 degrees
Congruency rules for Triangles - answer-angles opposite congruent sides are
congruent, sides opposite congruent angles are congruent, largest angle is
always opposite longest side, smallest angle is always opposite shortest side
