2 2/3 / 7/9

1 answer

To divide the mixed number \(2 \frac{2}{3}\) by the fraction \(\frac{7}{9}\), follow these steps:

  1. Convert the mixed number to an improper fraction: \[ 2 \frac{2}{3} = \frac{2 \times 3 + 2}{3} = \frac{6 + 2}{3} = \frac{8}{3} \]

  2. Dividing by a fraction is the same as multiplying by its reciprocal: \[ \frac{8}{3} \div \frac{7}{9} = \frac{8}{3} \times \frac{9}{7} \]

  3. Multiply the fractions: \[ \frac{8 \times 9}{3 \times 7} = \frac{72}{21} \]

  4. Simplify the fraction:

    • Find the greatest common divisor (GCD) of 72 and 21, which is 3.
    • Divide both the numerator and the denominator by 3: \[ \frac{72 \div 3}{21 \div 3} = \frac{24}{7} \]
  5. Convert back to a mixed number (if desired): \(\frac{24}{7} = 3 \frac{3}{7}\) (since \(24 \div 7 = 3\) remainder \(3\)).

So, the final answer is: \[ \frac{24}{7} \text{ or } 3 \frac{3}{7} \]
