 NEGATIONS FOR A OR B A AND B IF A THEN B FOR ALL x, A(x) THERE EXISTS X SUCH THAT A(x)" "A or B"      "not A and not B""A and B"    "not A or not B""if A, then B"      "A and not B" "For all x, A(x)""There exist x such that not A(x)" "There exists x such that A(x)""For every x, not A(x)" 1. A CIRCLE IS 3602. ARC = 203 SO, WHAT IS 20 /360= 1/184. WHATS 1/18 OF 72? 1/18 * 72/1= 4 A 20L SAMPLE OF WATER CONTAINS 1L OF POLLUTION. WHAT PERCENT OF THE SAMPLE IS POLLUTION? 1 / 20 = .05 = 5% DIVIDE THE WHOLE INTO THE PART TO GET PERCENT. YOUR SAMPLE IS 20. THE 1L IS WHAT YOUR PERCENTAGE IS COMING FROM. 20 IS THE WHOLE AND 1 IS THE PART. WHEN YOU DIVIDE 1 BY 20 YOU ARE GETTING A DECIMAL OR PART OF THE 20. THEN JUST CONVERT DECIMAL INTO PERCENT. CONVERT 3.2 INTO A FRACTION 3 2/10 = 3 1/5 (REDUCE!) COUNT THE DECIMAL PLACES.EACH DECIMAL NUMERAL CAN BE CHANGED TO A FRACTION JUST BY WRITING THE NUMBER IN FRACTION FORM AS IT READS. WHATS GREATER? 3/4 OR 2/3 1. FIND COMMON DENOMINATOR AND COMPARE.3 = 9    AND 2 = 84   12          3    12 9/12 > 8/12 (-5) - (+8) =? (-3) - (-4) = ? (-5) + (-8) = -13(-3) + (+4) = +1remember to change the sign and the 2nd integers property. 85 = R * 2 1/2 GET RID OF THE 2 1/2 1. CONVERT INTO IMPROPER FRACTION (5/2)2. DIVIDE BOTH SIDES RECIPROCAL (2/5). REMEMBER THAT MEANS THAT YOU FLIP THE ORIGINAL (5/2) AND MULTIPLY IT 2/5 * 5/2 = 1/1 = 1 100 CM = ?
