Step-by-Step Solution

To solve the problem, we start by finding the least common denominator (LCD) for the fractions 412 \frac{4}{12} , 13 \frac{1}{3} , and 16 \frac{1}{6} .

The denominators are 12, 3, and 6. We need to find the smallest number that is a multiple of each of these numbers. The LCD of 12, 3, and 6 is 12.

Next, we convert each fraction to have this common denominator:

  • 412 \frac{4}{12} already has 12 as the denominator.
  • 13 \frac{1}{3} can be converted to have 12 as the denominator by multiplying both the numerator and the denominator by 4: 13=1×43×4=412\frac{1}{3} = \frac{1 \times 4}{3 \times 4} = \frac{4}{12}.
  • 16 \frac{1}{6} can be converted to have 12 as the denominator by multiplying both the numerator and the denominator by 2: 16=1×26×2=212\frac{1}{6} = \frac{1 \times 2}{6 \times 2} = \frac{2}{12}.

Now, we simply add these fractions:

412+412+212=4+4+212=1012 \frac{4}{12} + \frac{4}{12} + \frac{2}{12} = \frac{4 + 4 + 2}{12} = \frac{10}{12} .

Therefore, the solution to the problem is 1012 \frac{10}{12} .

Answer

1012 \frac{10}{12}
