Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Multiply the numerators of the fractions together.
  • Step 2: Multiply the denominators of the fractions together.
  • Step 3: Simplify the resulting fraction, if possible.

Now, let's work through each step:
Step 1: Multiply the numerators: 2×3×4=24 2 \times 3 \times 4 = 24 .
Step 2: Multiply the denominators: 3×4×5=60 3 \times 4 \times 5 = 60 .
Step 3: The resulting fraction is 2460 \frac{24}{60} . Simplify by finding the greatest common divisor of 24 and 60, which is 12.

Divide both the numerator and the denominator by 12:
Numerator: 2412=2 \frac{24}{12} = 2
Denominator: 6012=5 \frac{60}{12} = 5
Thus, the simplified fraction is 25 \frac{2}{5} .

Therefore, the solution to the problem is 25 \frac{2}{5} .

Answer

25 \frac{2}{5}
