which number is halfway between 642,000 and 643,000? 642,050 642,500 643,050 643,500
Answer
Explanation:
Step1: Recall mid - point formula
The formula to find the number halfway between two numbers $a$ and $b$ is $\frac{a + b}{2}$. Here $a = 642000$ and $b=643000$.
Step2: Calculate the sum
$a + b=642000+643000 = 1285000$.
Step3: Divide by 2
$\frac{1285000}{2}=642500$.
Answer:
642,500
