Repaso de álgebra y geometría: Ordenar números reales

Ordena estos números de menor a mayor:

[tex] \[ -0 . \overline{6}, \sqrt{14}, 3.85, -\frac{34}{50} \] [/tex]

Answer :

Sure, let's look at how to order the given numbers from smallest to largest. The numbers we have are:

1. [tex]\(-0 . \overline{6}\)[/tex]
2. [tex]\(\sqrt{14}\)[/tex]
3. [tex]\(3.85\)[/tex]
4. [tex]\(-\frac{34}{50}\)[/tex]

### Step-by-Step Solution:

1. Convert each number into a common form for easy comparison:

- [tex]\(-0 . \overline{6}\)[/tex]: This is a repeating decimal, which is approximately [tex]\(-0.6666\)[/tex].

- [tex]\(\sqrt{14}\)[/tex]: Using a calculator, [tex]\(\sqrt{14}\)[/tex] is approximately [tex]\(3.7417\)[/tex].

- [tex]\(3.85\)[/tex]: This is already in decimal form.

- [tex]\(-\frac{34}{50}\)[/tex]: Simplify the fraction: [tex]\(-\frac{34}{50}\)[/tex] = [tex]\(-0.68\)[/tex].

2. List the approximate decimal values:
- [tex]\(-0.6666\)[/tex]
- [tex]\(3.7417\)[/tex]
- [tex]\(3.85\)[/tex]
- [tex]\(-0.68\)[/tex]

3. Order these values from smallest to largest:
- The smallest value is [tex]\(-0.68\)[/tex].
- Next is [tex]\(-0.6666\)[/tex].
- After that is [tex]\(3.7417\)[/tex] ([tex]\(\sqrt{14}\)[/tex]).
- The largest value is [tex]\(3.85\)[/tex].

### Ordered Numbers:
- [tex]\(-0.68\)[/tex]
- [tex]\(-0.6666\)[/tex]
- [tex]\(3.7417\)[/tex] ([tex]\(\sqrt{14}\)[/tex])
- [tex]\(3.85\)[/tex]

Thus, the numbers in order from smallest to largest are:
[tex]\[
-\frac{34}{50}, -0 . \overline{6}, \sqrt{14}, 3.85
\][/tex]
