The correct Answer is:
To solve the problem of finding the number by which `6 2/9` should be divided to obtain `4 2/3`, we can follow these steps: ### Step 1: Convert the mixed numbers to improper fractions. 1. **Convert `6 2/9`**: - Multiply the whole number (6) by the denominator (9): \( 6 \times 9 = 54 \) - Add the numerator (2) to this result: \( 54 + 2 = 56 \) - Therefore, \[ 6 \frac{2}{9} = \frac{56}{9} \] 2. **Convert `4 2/3`**: - Multiply the whole number (4) by the denominator (3): \( 4 \times 3 = 12 \) - Add the numerator (2) to this result: \( 12 + 2 = 14 \) - Therefore, \[ 4 \frac{2}{3} = \frac{14}{3} \] ### Step 2: Set up the equation. We want to find the number \( x \) such that: \[ \frac{56}{9} \div x = \frac{14}{3} \] This can be rewritten as: \[ \frac{56}{9} = x \times \frac{14}{3} \] ### Step 3: Solve for \( x \). To isolate \( x \), we can rearrange the equation: \[ x = \frac{56}{9} \div \frac{14}{3} \] Dividing by a fraction is the same as multiplying by its reciprocal: \[ x = \frac{56}{9} \times \frac{3}{14} \] ### Step 4: Simplify the expression. 1. Multiply the numerators: \[ 56 \times 3 = 168 \] 2. Multiply the denominators: \[ 9 \times 14 = 126 \] 3. Therefore, we have: \[ x = \frac{168}{126} \] ### Step 5: Simplify the fraction. To simplify \( \frac{168}{126} \): - Find the greatest common divisor (GCD) of 168 and 126, which is 42. - Divide both the numerator and the denominator by 42: \[ \frac{168 \div 42}{126 \div 42} = \frac{4}{3} \] ### Final Answer: Thus, the number by which `6 2/9` should be divided to obtain `4 2/3` is: \[ \frac{4}{3} \text{ or } 1 \frac{1}{3} \]
