Answer 1

To order the distances from least to greatest, we first need to evaluate each of the values provided:

1. 512 km - This is already a clear number, so we keep it as is.

2. √28 km - Calculating this using a calculator or estimating:

   • √28 = √(4*7) = 2√7 ≈ 2 * 2.64575 = 5.291. So, √28 ≈ 5.291 km.

3. 5.5̅ km (often written as \( \frac{5}{9} \) or repeated decimals) - This notation means that 5.5 repeats indefinitely, which is approximately 5.555... km, more exactly it is \( \frac{50}{9} \) which is around 5.555... km.

4. 234 km - This is also a clear number.

Now we can summarize the values we've computed:

• \( √28 ≈ 5.291 \) km
• \( 5.5̅ ≈ 5.555\) km
• 234 km
• 512 km

Now, let's compare them:

1. √28 ≈ 5.291 km
2. 5.5̅ ≈ 5.555 km
3. 234 km
4. 512 km

Ordering these from least to greatest:

1. √28
2. 5.5̅
3. 234
4. 512

So, the order from least to greatest is: √28, 5.5̅, 234, 512.
