It's easier to see the numbers if you use commas.
6,289,002
The 6 is in the millions place. When rounding, if the following number is 5 or higher, you would round up. If the following number is 4 or less, you would round down. The number following the 6 is a 2, so you would round down. The nearest million would be 6,000,000.

Answer:

Step-by-step explanation:

<h3>Rational number</h3>

$1) \dfrac{4}{5}+\dfrac{3}{8}\\\\\dfrac{4}{5} \ \text{is a rational number} \ and \ \dfrac{3}{8} \ \text{is a rational number}\\\\\dfrac{4}{5}+\dfrac{3}{8} \ \text{is also a rational number}$

$b) \sqrt{100}+\sqrt{5} = 10+\sqrt{5}\\\\\sqrt{5} \ \text{is a irrational number}. \\\\ \text{Rational number added to irrational number will result in an irrational number}\\\\10 + \sqrt{5} \ is \ not \ a \ rational \ number.$
