a) The halfway number is $\frac{-4.5}{10}$ .

b) The ascending order is $\frac{-1}{2}$ , $\frac{-4.5}{10}$ and $\frac{-2}{5}$ .

Step-by-step explanation:

a)Halfway number is otherwise Middle number.

The halfway number of two numbers = $\frac{sum of two numbers}{2}$ .

The halfway for $\frac{-2}{5}$ and $\frac{-2}{5}$ = $\frac{\frac{-2}{5}+ (\frac{-1}{2})}{2}$ .

= $\frac{-2}{5}+ (\frac{-1}{2})$ .

= $\frac{-4-5}{10}$ .

= $\frac{-9}{10}$ .

∴Halfway = $\frac{\frac{-9}{10} }{2}$ .

= $\frac{-4.5}{10}$

The halfway for $\frac{-2}{5}$ and $\frac{-1}{2}$ = $\frac{-4.5}{10}$ .

b) The ascending order is $\frac{-1}{2}$ , $\frac{-4.5}{10}$ and $\frac{-2}{5}$ .

What is 247,039 rounded to the nearest thousand

DerKrebs [107]

Answer:
247,000

Explanation:
To round a number to the nearest thousand, we check the digit in the hundreds position:
1- If the digit is less than 5, then we round down. This means that we simply convert all digits after the thousands to zero and that's it
2- If the digit is equal to or more than 5, then we round up. This means that we add one to the thousands digit and then convert all digits after the thousands to zero.

In the given number 247039, the number in the hundreds position is 0. This means that we will round down

Therefore, 246039 rounded to the nearest thousand would simply give 247000

Hope this helps :)
