Final answer:
Half of the expression 2a + 4b is found by dividing each term by 2, resulting in the expression a + 2b.
Step-by-step explanation:
To find half of the expression 2a + 4b, you simply divide each term inside the expression by 2. This is an application of the distributive property, where you distribute the division across the terms within the parentheses.
Let's break it down:
- Divide 2a by 2 to get a.
- Divide 4b by 2 to get 2b.
Therefore, half of 2a + 4b is a + 2b.
