Video Solution

Step-by-Step Solution

To solve the given problem, we'll follow these steps:

  • Convert the mixed numbers to improper fractions.
  • Multiply the improper fractions.
  • Simplify the result and convert back to a mixed number if necessary.

Let's work through these steps:

1. Convert each mixed number to an improper fraction:

  • For 24122\frac{4}{12}, first simplify the fraction 412\frac{4}{12} to 13\frac{1}{3}. So, 2132\frac{1}{3} becomes:
  • 2×3+13=73\frac{2 \times 3 + 1}{3} = \frac{7}{3}.

  • For 1241\frac{2}{4}, first simplify the fraction 24\frac{2}{4} to 12\frac{1}{2}. So, 1121\frac{1}{2} becomes:
  • 1×2+12=32\frac{1 \times 2 + 1}{2} = \frac{3}{2}.

2. Multiply the improper fractions:

The multiplication of 73\frac{7}{3} and 32\frac{3}{2} is:

73×32=216\frac{7}{3} \times \frac{3}{2} = \frac{21}{6}.

3. Simplify the resulting fraction 216\frac{21}{6}:

216=72\frac{21}{6} = \frac{7}{2} after dividing the numerator and denominator by 3.

4. Convert the improper fraction back to a mixed number:

72=312\frac{7}{2} = 3\frac{1}{2}.

Thus, the solution to the problem is 312\boxed{3\frac{1}{2}}.

Answer

312 3\frac{1}{2}
