Step-by-Step Solution

The problem requires multiplying the fractions 54 \frac{5}{4} , 12 \frac{1}{2} , and 36 \frac{3}{6} .

Step 1: Multiply the numerators.

We have: 5×1×3=15 5 \times 1 \times 3 = 15 .

Step 2: Multiply the denominators.

We have: 4×2×6=48 4 \times 2 \times 6 = 48 .

Step 3: Form the fraction from results of the two steps above.

The product of these fractions is 1548 \frac{15}{48} .

Step 4: Simplify the fraction.

To simplify 1548 \frac{15}{48} , we need to find the greatest common divisor (GCD) of 15 and 48. The GCD is 3.

Divide both the numerator and the denominator by their GCD:

15÷348÷3=516 \frac{15 \div 3}{48 \div 3} = \frac{5}{16} .

Thus, the simplified product of the fractions is 516 \frac{5}{16} .

We can compare it against the given answer choices to confirm:

  • Choice 1: 316 \frac{3}{16} - incorrect.
  • Choice 2: 516 \frac{5}{16} - correct.
  • Choice 3: 1548 \frac{15}{48} - correct but not simplified.
  • Choice 4: 1516 \frac{15}{16} - incorrect.

The correct answer choice is Choice 2, 516 \frac{5}{16} .

Answer

516 \frac{5}{16}
