ATI TEAS 6 study guide Math
(2025\2026) with verified questions &
actual answers
Decimal Placement/Converting - correct answer 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 - correct answer *TO* - Divide % by 100 then remove % symbol
*FROM* - Multiply by 100 then add % symbol
Divide % by 100 - correct answer How do you convert a percent into a decimal?
Percentage Convert to/from Fraction - correct answer *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 - correct answer Divide numerator by denominator
Order of Operations - correct answer -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 - correct answer -*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
<, _<_ - correct answer Less than, IS fewer than
Less than or equal to, is at most, is no more than
>, _>_ - correct answer Greater than, IS more than
Greater than or equal to, is at least, is no less than
= - correct answer Equal, equal to, is, was, were, will be, yields, becomes
Common Denominator - correct answer 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 - correct answer 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 - correct answer Incorrect
Story that is interesting containing details that aren't necessary to tell you what happened.
Erroneous - correct answer Irrelevant
Story might contain *conflicting* accounts of what happened due to having multiple observers.
