Step-by-Step Solution

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

  • Step 1: Identify the least common denominator (LCD) of the fractions 14 \frac{1}{4} and 12 \frac{1}{2} .
  • Step 2: Convert each fraction to have the common denominator.
  • Step 3: Add the fractions together.

Now, let's work through each step:

Step 1: Identify the Least Common Denominator (LCD).

The denominators are 4 and 2. The smallest number that both 4 and 2 can divide into without a remainder is 4. Thus, the LCD is 4.

Step 2: Convert each fraction to have the common denominator.

The fraction 14\frac{1}{4} already has the denominator 4, so it remains the same: 14\frac{1}{4}.

The fraction 12\frac{1}{2} needs to be converted. We multiply both the numerator and denominator by 2 to get the equivalent fraction 24\frac{2}{4}.

Step 3: Add the fractions.

The fractions 14\frac{1}{4} and 24\frac{2}{4} share a common denominator, so we can add the numerators:

14+24=1+24=34\frac{1}{4} + \frac{2}{4} = \frac{1 + 2}{4} = \frac{3}{4}.

Therefore, the solution to the problem is 34\frac{3}{4}.

Answer

34 \frac{3}{4}
