Step-by-step solution for: Grade 6 Adding Mixed Numbers Worksheets | Math Worksheets
Let's solve each of these subtracting mixed numbers problems step by step. We'll convert the mixed numbers to improper fractions, find a common denominator, subtract, and then simplify or convert back to mixed numbers as needed.
---
- Convert to improper fractions:
- $ 2\frac{4}{9} = \frac{2 \times 9 + 4}{9} = \frac{18 + 4}{9} = \frac{22}{9} $
- $ 1\frac{4}{6} = \frac{1 \times 6 + 4}{6} = \frac{10}{6} $
- Simplify $ \frac{10}{6} = \frac{5}{3} $
- Find common denominator: LCM of 9 and 3 is 9
- $ \frac{5}{3} = \frac{15}{9} $
- Subtract: $ \frac{22}{9} - \frac{15}{9} = \frac{7}{9} $
✔ Answer: $ \frac{7}{9} $
---
- Convert:
- $ 9\frac{1}{2} = \frac{19}{2} $
- $ 5\frac{1}{4} = \frac{21}{4} $
- Common denominator: LCM of 2 and 4 is 4
- $ \frac{19}{2} = \frac{38}{4} $
- Subtract: $ \frac{38}{4} - \frac{21}{4} = \frac{17}{4} $
- Convert to mixed number: $ \frac{17}{4} = 4\frac{1}{4} $
✔ Answer: $ 4\frac{1}{4} $
---
- Convert:
- $ 7\frac{1}{3} = \frac{22}{3} $
- $ 4\frac{1}{6} = \frac{25}{6} $
- Common denominator: LCM of 3 and 6 is 6
- $ \frac{22}{3} = \frac{44}{6} $
- Subtract: $ \frac{44}{6} - \frac{25}{6} = \frac{19}{6} $
- Convert: $ \frac{19}{6} = 3\frac{1}{6} $
✔ Answer: $ 3\frac{1}{6} $
---
- Convert:
- $ 7\frac{1}{2} = \frac{15}{2} $
- $ 3\frac{5}{6} = \frac{23}{6} $
- Common denominator: LCM of 2 and 6 is 6
- $ \frac{15}{2} = \frac{45}{6} $
- Subtract: $ \frac{45}{6} - \frac{23}{6} = \frac{22}{6} = \frac{11}{3} $
- Convert: $ \frac{11}{3} = 3\frac{2}{3} $
✔ Answer: $ 3\frac{2}{3} $
---
- Same denominators, so subtract whole numbers and fractions:
- $ 11 - 5 = 6 $
- $ \frac{3}{4} - \frac{1}{4} = \frac{2}{4} = \frac{1}{2} $
✔ Answer: $ 6\frac{1}{2} $
---
- Simplify $ \frac{2}{4} = \frac{1}{2} $
- So $ 8\frac{1}{2} = \frac{17}{2} $
