Subtracting Mixed Numbers with Regrouping
Steps for solving subtraction of mixed numbers with unlike denominators: • Find the LCD • Write equivalent fractions • Subtract the fractions, regroup if necessary, then subtract the whole numbers • Simplify the answer
LowestTerms LCD Problem = Equivalent Fraction 3 5 4 5 - 3 2 5
LowestTerms LCD Problem = Equivalent Fraction 4 5 4 4 = + 4 4 – – 3 1 = 4
LowestTerms LCD Problem = Equivalent Fraction 3 5 8 13 x 1= 3 8 – 8 4-4,8 4 = = + 8 8 8 x 1= 6 6 x 2= 2 2 LCD = 8 – = 8 – 8 x 2= 7 1 8
