Problem: Multiplying Mixed Numbers
The task involves multiplying mixed numbers. To solve these problems, we will follow these steps:
1. Convert each mixed number to an improper fraction.
2. Multiply the numerators together and the denominators together.
3. Simplify the resulting fraction if possible.
4. Convert the result back to a mixed number if necessary.
Let's solve each problem step by step.
---
Problem 1: \( 4 \frac{9}{10} \times 4 \frac{1}{2} \)
#### Step 1: Convert mixed numbers to improper fractions.
- \( 4 \frac{9}{10} = \frac{(4 \times 10) + 9}{10} = \frac{40 + 9}{10} = \frac{49}{10} \)
- \( 4 \frac{1}{2} = \frac{(4 \times 2) + 1}{2} = \frac{8 + 1}{2} = \frac{9}{2} \)
#### Step 2: Multiply the fractions.
\[
\frac{49}{10} \times \frac{9}{2} = \frac{49 \times 9}{10 \times 2} = \frac{441}{20}
\]
#### Step 3: Convert the result to a mixed number.
- Divide 441 by 20: \( 441 \div 20 = 22 \) remainder \( 1 \).
- So, \( \frac{441}{20} = 22 \frac{1}{20} \).
#### Final Answer:
\[
\boxed{22 \frac{1}{20}}
\]

Problem 2: \( 2 \frac{1}{2} \times 3 \frac{3}{5} \)
#### Step 1: Convert mixed numbers to improper fractions.
- \( 2 \frac{1}{2} = \frac{(2 \times 2) + 1}{2} = \frac{4 + 1}{2} = \frac{5}{2} \)
- \( 3 \frac{3}{5} = \frac{(3 \times 5) + 3}{5} = \frac{15 + 3}{5} = \frac{18}{5} \)
#### Step 2: Multiply the fractions.
\[
\frac{5}{2} \times \frac{18}{5} = \frac{5 \times 18}{2 \times 5} = \frac{90}{10} = 9
\]
#### Final Answer:
\[
\boxed{9}
\]

Problem 3: \( 2 \frac{1}{2} \times 4 \frac{1}{3} \)
#### Step 1: Convert mixed numbers to improper fractions.
- \( 2 \frac{1}{2} = \frac{(2 \times 2) + 1}{2} = \frac{4 + 1}{2} = \frac{5}{2} \)
- \( 4 \frac{1}{3} = \frac{(4 \times 3) + 1}{3} = \frac{12 + 1}{3} = \frac{13}{3} \)
#### Step 2: Multiply the fractions.
\[
\frac{5}{2} \times \frac{13}{3} = \frac{5 \times 13}{2 \times 3} = \frac{65}{6}
\]
#### Step 3: Convert the result to a mixed number.
- Divide 65 by 6: \( 65 \div 6 = 10 \) remainder \( 5 \).
- So, \( \frac{65}{6} = 10 \frac{5}{6} \).
#### Final Answer:
\[
\boxed{10 \frac{5}{6}}
\]

#### Step 1: Convert mixed numbers to improper fractions.
- \( 3 \frac{1}{2} = \frac{(3 \times 2) + 1}{2} = \frac{6 + 1}{2} = \frac{7}{2} \)
- \( 3 \frac{2}{3} = \frac{(3 \times 3) + 2}{3} = \frac{9 + 2}{3} = \frac{11}{3} \)
#### Step 2: Multiply the fractions.
\[
\frac{7}{2} \times \frac{11}{3} = \frac{7 \times 11}{2 \times 3} = \frac{77}{6}
\]
#### Step 3: Convert the result to a mixed number.
- Divide 77 by 6: \( 77 \div 6 = 12 \) remainder \( 5 \).
- So, \( \frac{77}{6} = 12 \frac{5}{6} \).
#### Final Answer:
\[
\boxed{12 \frac{5}{6}}

Problem 5: \( 3 \frac{1}{2} \times 2 \frac{2}{3} \)
#### Step 1: Convert mixed numbers to improper fractions.
- \( 3 \frac{1}{2} = \frac{(3 \times 2) + 1}{2} = \frac{6 + 1}{2} = \frac{7}{2} \)
- \( 2 \frac{2}{3} = \frac{(2 \times 3) + 2}{3} = \frac{6 + 2}{3} = \frac{8}{3} \)
#### Step 2: Multiply the fractions.
\[
\frac{7}{2} \times \frac{8}{3} = \frac{7 \times 8}{2 \times 3} = \frac{56}{6}
\]
#### Step 3: Simplify the fraction.
- Simplify \( \frac{56}{6} \) by dividing numerator and denominator by their greatest common divisor (GCD), which is 2:
\[
\frac{56 \div 2}{6 \div 2} = \frac{28}{3}
\]
#### Step 4: Convert the result to a mixed number.
- Divide 28 by 3: \( 28 \div 3 = 9 \) remainder \( 1 \).
- So, \( \frac{28}{3} = 9 \frac{1}{3} \).
#### Final Answer:
\[
\boxed{9 \frac{1}{3}}
\]

Problem 8: \( 4 \frac{4}{5} \times 4 \frac{1}{3} \)
#### Step 1: Convert mixed numbers to improper fractions.
- \( 4 \frac{4}{5} = \frac{(4 \times 5) + 4}{5} = \frac{20 + 4}{5} = \frac{24}{5} \)
- \( 4 \frac{1}{3} = \frac{(4 \times 3) + 1}{3} = \frac{12 + 1}{3} = \frac{13}{3} \)
#### Step 2: Multiply the fractions.
\[
\frac{24}{5} \times \frac{13}{3} = \frac{24 \times 13}{5 \times 3} = \frac{312}{15}
\]
#### Step 3: Simplify the fraction.
- Simplify \( \frac{312}{15} \) by dividing numerator and denominator by their greatest common divisor (GCD), which is 3:
\[
\frac{312 \div 3}{15 \div 3} = \frac{104}{5}
\]
#### Step 4: Convert the result to a mixed number.
