Decimal Placement/Converting - - 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 - *TO* - Divide % by 100 then remove % symbol
*FROM* - Multiply by 100 then add % symbol
Divide % by 100 - How do you convert a percent into a decimal?
Percentage Convert to/from Fraction - *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 - Divide numerator by denominator
Order of Operations - -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 - -*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
