ATI TEAS 6 STUDY GUIDE MATH 100%
VERIFIED.
Decimal Placement/Converting - ANS - Value greater than 1, Move decimal to right till you
get whole number.
- Number becomes numerator and 1 becomes denominator with the number of 0's that
matches number of moves for decimal. = *Fraction*
- Value less than 1. Use whole number as numerator and the *Place value* of *last decimal
Digit* as denominator. =*Fraction*
Percentage Convert to/from Decimal - ANS *TO* - Divide % by 100 then remove % symbol
*FROM* - Multiply by 100 then add % symbol
Divide % by 100 - ANS How do you convert a percent into a decimal?
Percentage Convert to/from Fraction - ANS *TO* - Convert to decimal first (divide by 100)
then put into simplest form
*FROM* - Convert to decimal (multiply to get 100 in denominator then divide by denominator)
then put decimal into %
Fraction Convert to Decimal - ANS Divide numerator by denominator
Order of Operations - ANS -PEMDAS (No exponent for TEAS 6)
-Parentheses *FIRST*
-Multiplication and Division *SECOND* (Left to Right)

, -Addition and Subtraction *THIRD* (Left to Right)
Compare and Order Rational Numbers - ANS -*Rational Numbers*: -6 (-6/1), 5 (5/1), 100
(100/1)
-*Irrational Numbers*: Square root (any prime number), pi
-*Numeric Order*: Least to Greatest, Greatest to Least. Best in decimal form. Line them up
vertically.
-*Fraction/Fraction Form*: 5 2/7 (put into decimal) Divide 2 by 7 to get .2857 which will equal
5.2857
<, _<_ - ANS Less than, IS fewer than
Less than or equal to, is at most, is no more than
>, _>_ - ANS Greater than, IS more than
Greater than or equal to, is at least, is no less than
= - ANS Equal, equal to, is, was, were, will be, yields, becomes
Common Denominator - ANS 1. Find least on on multiple of denominator
2. Change each fraction to make their denominator the same as least common denominator
~List multiples of each denominator and find SMALLEST number
~Multiply numerator by multiple of LCD, Use LCD as denominator
Solve Equations in One Variable - ANS Collecting all variable terms to *one* side of the equal
sign and all the constants on the other side, using addition or subtraction. Once all like terms
are combined, last step is to divide. Could also be multiplication by the reciprocal ( One divided
by original number).
Extraneous - ANS Incorrect
Story that is interesting containing details that aren't necessary to tell you what happened.
