Step-by-Step Solution

To solve the problem of adding the fractions 12\frac{1}{2} and 46\frac{4}{6}, we start by finding the least common denominator (LCD).

First, we identify the denominators: 2 and 6. The least common multiple of 2 and 6 is 6, which will be our LCD.

Next, we convert each fraction to have the denominator of 6:

  • Convert 12\frac{1}{2} to an equivalent fraction with a denominator of 6. Since 23=62 \cdot 3 = 6, multiply the numerator by 3: 1×32×3=36\frac{1 \times 3}{2 \times 3} = \frac{3}{6}.

  • The fraction 46\frac{4}{6} already has the desired common denominator.

Now that the fractions are 36\frac{3}{6} and 46\frac{4}{6}, we can add them:

36+46=3+46=76\frac{3}{6} + \frac{4}{6} = \frac{3+4}{6} = \frac{7}{6}.

The solution to the problem is 76\frac{7}{6}, which matches choice 2.

Answer

76 \frac{7}{6}
