The correct Answer is:
To find the other number when the product of two numbers is \( 15 \frac{5}{6} \) and one of the numbers is \( 6 \frac{1}{3} \), we can follow these steps: ### Step 1: Convert Mixed Numbers to Improper Fractions First, we need to convert the mixed numbers into improper fractions. For \( 15 \frac{5}{6} \): \[ 15 \frac{5}{6} = \frac{15 \times 6 + 5}{6} = \frac{90 + 5}{6} = \frac{95}{6} \] For \( 6 \frac{1}{3} \): \[ 6 \frac{1}{3} = \frac{6 \times 3 + 1}{3} = \frac{18 + 1}{3} = \frac{19}{3} \] ### Step 2: Set Up the Equation Let the other number be \( x \). According to the problem, the product of the two numbers is: \[ \frac{19}{3} \times x = \frac{95}{6} \] ### Step 3: Solve for \( x \) To find \( x \), we can rearrange the equation: \[ x = \frac{95}{6} \div \frac{19}{3} \] Dividing by a fraction is the same as multiplying by its reciprocal: \[ x = \frac{95}{6} \times \frac{3}{19} \] ### Step 4: Simplify the Expression Now we can simplify: \[ x = \frac{95 \times 3}{6 \times 19} \] Calculating the numerator: \[ 95 \times 3 = 285 \] Calculating the denominator: \[ 6 \times 19 = 114 \] So we have: \[ x = \frac{285}{114} \] ### Step 5: Simplify the Fraction Now we simplify \( \frac{285}{114} \): Both 285 and 114 can be divided by 3: \[ \frac{285 \div 3}{114 \div 3} = \frac{95}{38} \] ### Step 6: Convert to Mixed Number To convert \( \frac{95}{38} \) to a mixed number: \[ 95 \div 38 = 2 \quad \text{(with a remainder of 19)} \] So, \[ \frac{95}{38} = 2 \frac{19}{38} \] ### Final Answer Therefore, the other number is: \[ 2 \frac{19}{38} \] ---
