RN Subtracting Mixed Fractions
 The least common denominator for this problem isTo subtract mixed fractions, the first step is to find thecommon denominator and make new equivalent fractions.  To find the common denominator, listthe multiples of the denominators until you find a common one.3:  3, 6, 9, 12, 15, 18, 21, ...7:  7, 14, 21, 28, 35, ...-521573 After this you make new equivalent fractions with thecommon denominator.-521573x 3x 3x 7x 7==52212115 Now subtract whole numbers and numerators.  Neversubtract denominators.  -521573x 3x 3x 7x 7==5232121 72115 The least common denominator for this problem isTo subtract mixed fractions, the first step is to find thecommon denominator and make new equivalent fractions.  To find the common denominator, listthe multiples of the denominators until you find a common one.3:  3, 6, 9, 12, 15....4:  4, 8, 12, 16, 20...-543234 After this you make new equivalent fractions with thecommon denominator.-543234x 4 x 4 x 3 x 3 ==5412128 -Now subtract whole numbers and numerators.  Neversubtract denominators.  However, on this problemwe can not subtract 9 from 8 so we have to take onefrom the 5 and rename it to 12/12s.54final answer121298=4+1212+128=-44201212129 The least common denominator for this problem isTo subtract mixed fractions, the first step is to find thecommon denominator and make new equivalent fractions.  To find the common denominator, listthe multiples of the denominators until you find a common one.New problem.5:  5, 10, 15, 20,...3:  3, 6, 9, 12, 15,...-742253 After this you make new equivalent fractions with thecommon denominator.-742253x 3 x 3x 5x 5 ==7415156 -Now subtract whole numbers and numerators.  Neversubtract denominators.  However, on this problemwe can not subtract 10 from 6 so we have to take onefrom the 7 and rename it.Make sure the final answer is simplified.741015156=6+1515+156=-2641021151515 The least common denominator for this problem isTo subtract mixed fractions, the first step is to find thecommon denominator and make new equivalent fractions.  To find the common denominator, listthe multiples of the denominators until you find a common one.4:  4, 8, 12, ...2:  2, 4, ...-531142 After this you make new equivalent fractions with thecommon denominator.-531142x 2x 2==53 414 -Now subtract whole numbers and numerators.  Neversubtract denominators.  Here again we can not subtract2 from 1 so we take from the whole number.53 4 421=4+ 4 4+ 41=-143 5 4 4 42 -New problem!Think money!  Could we take 3 dollars and 3 quartersaway from 5 dollars?  No!  We would need change.How many quarters would we get for one dollar?53 43=4+ 4 4=-431 4 4 4 43 Think money!  Could we take 3 dollars and 3 quartersaway from \$5 and one quarter?  No!  We would need change.  How many quarters would we get for one dollar?  How many quarters did we already have?-Make sure its simplified.53 4 413=4+ 4 4+ 41=-431 5 4 4 43=12 -Now you solve.214123x 3x 3x 4x 4==-12 31212==-1112 812 312+1212= -Now you solve.615223==-16==-451 -Now you solve.813256==-18==-671 Now you solve.Did yousimplify?-155616 Now you solve.You mustrename.Did yousimplify?-151656 Now you solve.-191356 Now you solve.-241256 Now you solve.-193416 Now you solve.-143456 Now you solve.-145634 Now you solve.-1434 Now you solve.-1456 Now you solve.-1434 Now you solve.-365623 Now you solve.-361623 Now you solve.-381613
