Step-by-Step Solution

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

  • Step 1: Identify the least common denominator (LCD) for the given fractions.
  • Step 2: Convert each fraction to an equivalent fraction with this common denominator.
  • Step 3: Add the numerators, keeping the denominator unchanged.
  • Step 4: Simplify the resultant fraction if possible.

Now, let's work through each step:

Step 1: Identify the least common denominator (LCD).
The denominators are 6 and 12. The smallest number that both 6 and 12 divide evenly into is 12. Therefore, the LCD is 12.

Step 2: Convert the fractions to have the LCD as their denominator.
26\frac{2}{6} needs to be converted to a fraction with a denominator of 12. We multiply both the numerator and denominator by 2:

2×26×2=412\frac{2 \times 2}{6 \times 2} = \frac{4}{12}.

The second fraction, 512\frac{5}{12}, already has the denominator of 12, so it remains 512\frac{5}{12}.

Step 3: Add the two fractions:
412+512=4+512=912\frac{4}{12} + \frac{5}{12} = \frac{4 + 5}{12} = \frac{9}{12}.

Step 4: Simplify the fraction.
The fraction 912\frac{9}{12} can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 3:

9÷312÷3=34\frac{9 \div 3}{12 \div 3} = \frac{3}{4}.

Therefore, after fully simplifying, the sum of the fractions is 34 \frac{3}{4} .

Answer

912 \frac{9}{12}
