Find two rational number and two irrational number between 1/8 and 2/9.

To find two rational numbers and two irrational numbers between \(\frac{1}{8}\) and \(\frac{2}{9}\), we first need to understand these values as decimals:

\[
\frac{1}{8} = 0.125
\]

\[
\frac{2}{9} \approx 0.2222\ldots
\]

### 1. Two Rational Numbers:
Rational numbers can be expressed as fractions of two integers. Between 0.125 and 0.2222, we can easily find several rational numbers:

1. \( \frac{2}{15} \approx 0.1333\)
2. \( \frac{3}{20} = 0.15\)

### 2. Two Irrational Numbers:
Irrational numbers are non-repeating, non-terminating decimals. Examples include numbers like \( \sqrt{2} \), \( \pi \), and \( e \). We need to select numbers between 0.125 and 0.2222:

1. \( \sqrt{0.02} \approx 0.1414\ldots \)
2. \( \sqrt{0.05} \approx 0.2236\ldots \) (but we can also pick \( \sqrt{0.03} \approx 0.1732\ldots \))

These values meet the criteria and lie between 0.125 and 0.2222.
