Find the sum of 1/4 and 1/2.

To find the sum of 1/4 and 1/2, the first step is to ensure that both fractions have a common denominator. The denominator of the first fraction, 1/4, is 4, while the denominator of the second fraction, 1/2, is 2. The least common denominator (LCD) for these two fractions is 4.

Next, we need to express 1/2 with the common denominator of 4. We can achieve this by multiplying the numerator and denominator of 1/2 by 2:

1/2 = (1 × 2) / (2 × 2) = 2/4.

Now that both fractions have the same denominator, we can add them together:

1/4 + 2/4 = (1 + 2)/4 = 3/4.

Thus, the sum of 1/4 and 1/2 is 3/4. The correct answer reflects this calculation accurately, showing how to combine fractions with different denominators using a common denominator.
