Step-by-Step Solution

The multiplication of fractions 78\frac{7}{8} and 46\frac{4}{6} requires the direct operation of multiplying numerators with numerators and denominators with denominators.

  • Multiply the numerators: 7×4=287 \times 4 = 28
  • Multiply the denominators: 8×6=488 \times 6 = 48
  • Form the resulting fraction: 2848\frac{28}{48}

Now, we need to simplify 2848\frac{28}{48}. Find the greatest common divisor (GCD) of 28 and 48, which is 4.

  • Divide both numerator and denominator by their GCD: 28÷448÷4=712\frac{28 \div 4}{48 \div 4} = \frac{7}{12}

Therefore, the solution to the problem is 712\frac{7}{12}.

Thus, the correct answer is 712\frac{7}{12}, which corresponds to choice 3.

Answer

712 \frac{7}{12}
