To find the result of adding 1/2 and 1/4, it’s important to use a common denominator. The denominators in this case are 2 and 4. The least common denominator is 4.

First, convert 1/2 to a fraction with a denominator of 4. You can do this by multiplying both the numerator and denominator of 1/2 by 2, resulting in 2/4.

Now, you can add the two fractions:

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

Thus, the sum of 1/2 and 1/4 is 3/4, making it the correct answer. Understanding how to find a common denominator and convert fractions is crucial for successfully adding them.
