Step-by-Step Solution

To solve this problem, we'll convert the mixed numbers into improper fractions, multiply them, and simplify the result:

  • Step 1: Convert mixed numbers to improper fractions.
    • 1451\frac{4}{5} becomes 1×5+45=95\frac{1 \times 5 + 4}{5} = \frac{9}{5}.
    • 1131\frac{1}{3} becomes 1×3+13=43\frac{1 \times 3 + 1}{3} = \frac{4}{3}.
  • Step 2: Multiply the improper fractions.
    • 95×43=9×45×3=3615\frac{9}{5} \times \frac{4}{3} = \frac{9 \times 4}{5 \times 3} = \frac{36}{15}.
  • Step 3: Simplify the fraction 3615\frac{36}{15}.
    • The greatest common divisor of 36 and 15 is 3.
    • 36÷315÷3=125\frac{36 \div 3}{15 \div 3} = \frac{12}{5}.
  • Step 4: Convert the improper fraction 125\frac{12}{5} back to a mixed number.
    • 12÷512 \div 5 is 2 with a remainder of 2.
    • The mixed number is 2252\frac{2}{5}.

Therefore, the product of 145×113 1\frac{4}{5} \times 1\frac{1}{3} is 225 2\frac{2}{5} .

Answer

225 2\frac{2}{5}
