Example 5

medium
Multiply 213ร—1122\frac{1}{3} \times 1\frac{1}{2}.

Solution

  1. 1
    Convert each mixed number to an improper fraction: 213=2ร—3+13=732\frac{1}{3} = \frac{2 \times 3 + 1}{3} = \frac{7}{3} and 112=1ร—2+12=321\frac{1}{2} = \frac{1 \times 2 + 1}{2} = \frac{3}{2}.
  2. 2
    Multiply the improper fractions: 73ร—32=7ร—33ร—2=216\frac{7}{3} \times \frac{3}{2} = \frac{7 \times 3}{3 \times 2} = \frac{21}{6}.
  3. 3
    Simplify: gcdโก(21,6)=3\gcd(21, 6) = 3, so 216=72\frac{21}{6} = \frac{7}{2}.
  4. 4
    Convert back to a mixed number: 72=312\frac{7}{2} = 3\frac{1}{2}.

Answer

3123\frac{1}{2}
To multiply mixed numbers, first convert them to improper fractions, multiply numerators and denominators, simplify, and convert back to a mixed number if desired.
