Let's visualize fractions using a pie chart. When we talk about 3/4 and 1/2, we're referring to parts of a whole. Think of it like slicing a pizza or a pie.

Understanding Common Denominators

To add 3/4 and 1/2, we first need a common denominator. The common denominator of 4 and 2 is 4. So, 1/2 can be converted to 2/4. Now, we can easily add 3/4 and 2/4.

Step-by-Step Addition

1. Convert both fractions to have a common denominator.
2. Add the numerators.
3. Simplify if needed.
Example: 3/4 + 1/2 = 3/4 + 2/4 = 5/4 = 1 1/4
