A. [tex]500 \div 1000=0.5[/tex]
B. [tex]1000 \div 500=2[/tex]
C. [tex]1000+500=1500[/tex]
D. [tex]1000 \times 0.5=500[/tex]

To determine which equation correctly shows how to calculate the birthrate of a population, let's break down the problem step-by-step:

1. Understanding Birthrate Calculation:
- Birthrate is calculated as the number of new individuals born divided by the initial population size.

2. Given Data:
- Initial population: 1000 individuals
- Number of new individuals born: 500 individuals

3. Calculating the Birthrate:
- Birthrate = Number of new individuals born / Initial population
- Birthrate = 500 / 1000

4. Simplifying the Fraction:
- \( \frac{500}{1000} = 0.5 \)

Therefore, the correct equation that shows the calculation of the birthrate is:
[tex]\[ 500 \div 1000 = 0.5 \][/tex]

Among the given options:

A. \( 500 \div 1000 = 0.5 \)
B. \( 1000 \div 500 = 2 \)
C. \( 1000 + 500 = 1500 \)
D. \( 1000 \times 0.5 = 500 \)

The correct answer is:

A. [tex]\( 500 \div 1000 = 0.5 \)[/tex]
