The correct Answer is:
To find the product of the mixed fractions \( 7\frac{1}{4} \times 2\frac{3}{16} \times 2\frac{2}{7} \), we will follow these steps: ### Step 1: Convert Mixed Numbers to Improper Fractions 1. Convert \( 7\frac{1}{4} \) to an improper fraction: \[ 7\frac{1}{4} = \frac{7 \times 4 + 1}{4} = \frac{28 + 1}{4} = \frac{29}{4} \] 2. Convert \( 2\frac{3}{16} \) to an improper fraction: \[ 2\frac{3}{16} = \frac{2 \times 16 + 3}{16} = \frac{32 + 3}{16} = \frac{35}{16} \] 3. Convert \( 2\frac{2}{7} \) to an improper fraction: \[ 2\frac{2}{7} = \frac{2 \times 7 + 2}{7} = \frac{14 + 2}{7} = \frac{16}{7} \] ### Step 2: Write the Product of Improper Fractions Now we can write the product of the three improper fractions: \[ \frac{29}{4} \times \frac{35}{16} \times \frac{16}{7} \] ### Step 3: Simplify the Expression Before multiplying, we can simplify: - The \( 16 \) in the numerator of \( \frac{16}{7} \) cancels with the \( 16 \) in the denominator of \( \frac{35}{16} \): \[ \frac{29}{4} \times \frac{35}{1} \times \frac{1}{7} \] ### Step 4: Multiply the Numerators and Denominators Now we multiply the numerators and the denominators: \[ \text{Numerator: } 29 \times 35 = 1015 \] \[ \text{Denominator: } 4 \times 7 = 28 \] So, we have: \[ \frac{1015}{28} \] ### Step 5: Convert to Mixed Number Now we convert \( \frac{1015}{28} \) to a mixed number: 1. Divide \( 1015 \) by \( 28 \): - \( 28 \) goes into \( 1015 \) \( 36 \) times (since \( 28 \times 36 = 1008 \)). - The remainder is \( 1015 - 1008 = 7 \). So, we can write: \[ \frac{1015}{28} = 36\frac{7}{28} \] ### Step 6: Simplify the Fraction Part The fraction \( \frac{7}{28} \) simplifies to \( \frac{1}{4} \): \[ 36\frac{1}{4} \] ### Final Answer Thus, the final answer is: \[ \boxed{36\frac{1}{4}} \]
