A. 8.33 8 2/3 B. 8 2/3 - 8.33 C. 8.33 = 8 2/3 D. 8 2/3 - 8.33 B. 8 2/3 - 8.33 which of the following is 25% of 680 pounds? A. 1,700 pounds B. 510 pounds C. 68 pounds D. 170 pounds D. 170 pounds The success rate for a salesperson is 1 out of 8 calls. At this rate, how many sales would the salesperson expect to get out of 32 calls? A. 8 B. 256 C. 0.128 D. 4 D. 4 Tom is saving money to go to a concert. From his part-time job, he is able to save $18.50 per week. His older bro gave him $25 to start with. If W= number of weeks, which of the following expressions represents the number of weeks until Tom has saved at least $235? A. 8.50W + 25 = 235 B. (25 + 18.50)W - 235 C. 12.50W + 25 - 235 D. 12.50W + 25 235 C. 12.50W + 25 - 235 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 Percentage Convert to/from Fraction simplest form *TO* - Convert to decimal first (divide by 100) then put into *FROM* - Convert to decimal (multiply to get 100 in denominator then divide by denominator) then put decimal into % Fraction Convert to Decimal Order of Operations Divide numerator by denominator -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 , __ Less than, IS fewer than Less than or equal to, is at most, is no more than , __ Greater than, IS more than Greater than or equal to, is at least, is no less than = Equal, equal to, is, was, were, will be, yields, becomes Common Denominator 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 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 Incorrect Story that is interesting containing details that aren't necessary to tell you what happened.
