Verified step by step guidance
1
First, convert the mixed numbers to improper fractions. For \(3\frac{1}{4}\), multiply 3 by 4 and add 1 to get the numerator: \(3 \times 4 + 1 = 13\). So, \(3\frac{1}{4} = \frac{13}{4}\).
Next, convert \(1\frac{2}{3}\) to an improper fraction. Multiply 1 by 3 and add 2 to get the numerator: \(1 \times 3 + 2 = 5\). So, \(1\frac{2}{3} = \frac{5}{3}\).
Now, multiply the two improper fractions: \(\frac{13}{4} \times \frac{5}{3}\).
Multiply the numerators together: \(13 \times 5 = 65\).
Multiply the denominators together: \(4 \times 3 = 12\). The result is \(\frac{65}{12}\).

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Multiplication of Fractions
To multiply fractions, you multiply the numerators together and the denominators together. For example, when multiplying 3/4 by 1/3, you calculate (3*1)/(4*3) = 3/12, which can be simplified to 1/4. This process is essential for solving problems involving fractions.
A mixed number consists of a whole number and a proper fraction, such as 1(2/3). To perform operations with mixed numbers, convert them to improper fractions first. For instance, 1(2/3) becomes (3*1 + 2)/3 = 5/3. This conversion is crucial for accurate calculations.
Simplifying fractions involves reducing them to their lowest terms by dividing the numerator and denominator by their greatest common divisor (GCD). For example, the fraction 3/12 can be simplified to 1/4 by dividing both the numerator and denominator by 3. This step ensures that the final answer is presented in its simplest form.
