To find a rational number (fraction in simplest form) between \( 6 \) and \( 6 \frac{1}{4} \), we can first convert \( 6 \frac{1}{4} \) into an improper fraction.
1. Convert \( 6 \frac{1}{4} \):
\[
6 \frac{1}{4} = 6 + \frac{1}{4} = \frac{6 \times 4}{4} + \frac{1}{4} = \frac{24}{4} + \frac{1}{4} = \frac{25}{4}
\]
Now we need to find a rational number between \( 6 \) (which can be written as \( \frac{24}{4} \)) and \( \frac{25}{4} \).
2. The simplest way to find a rational number between \( \frac{24}{4} \) and \( \frac{25}{4} \) is to take the average of the two fractions:
\[
\text{Average} = \frac{\frac{24}{4} + \frac{25}{4}}{2}
\]
Combine the fractions:
\[
= \frac{\frac{24 + 25}{4}}{2} = \frac{\frac{49}{4}}{2} = \frac{49}{4} \times \frac{1}{2} = \frac{49}{8}
\]
3. Now, \( \frac{49}{8} \) is a rational number between \( 6 \) and \( 6\frac{1}{4} \). To confirm:
- Convert \( 6 \) to eighths:
\[
6 = \frac{48}{8}
\]
- Convert \( 6\frac{1}{4} \) to eighths:
\[
6\frac{1}{4} = \frac{25}{4} = \frac{50}{8}
\]
Since \( \frac{48}{8} < \frac{49}{8} < \frac{50}{8} \), it confirms that \( \frac{49}{8} \) is indeed between \( 6 \) and \( 6 \frac{1}{4} \).
4. Lastly, check if \( \frac{49}{8} \) is in simplest form:
- The greatest common divisor (GCD) of 49 and 8 is 1 (since 49 is \( 7^2 \) and 8 is \( 2^3 \)).
- Thus \( \frac{49}{8} \) is already in simplest form.
Therefore, the rational number between \( 6 \) and \( 6 \frac{1}{4} \) is:
\[
\frac{49}{8}
\]
1. Convert \( 6 \frac{1}{4} \):
\[
6 \frac{1}{4} = 6 + \frac{1}{4} = \frac{6 \times 4}{4} + \frac{1}{4} = \frac{24}{4} + \frac{1}{4} = \frac{25}{4}
\]
Now we need to find a rational number between \( 6 \) (which can be written as \( \frac{24}{4} \)) and \( \frac{25}{4} \).

\[
= \frac{\frac{24 + 25}{4}}{2} = \frac{\frac{49}{4}}{2} = \frac{49}{4} \times \frac{1}{2} = \frac{49}{8}
\]
3. Now, \( \frac{49}{8} \) is a rational number between \( 6 \) and \( 6\frac{1}{4} \). To confirm:
- Convert \( 6 \) to eighths:
\[
6 = \frac{48}{8}
\]
- Convert \( 6\frac{1}{4} \) to eighths:
\[
6\frac{1}{4} = \frac{25}{4} = \frac{50}{8}
\]
Since \( \frac{48}{8} < \frac{49}{8} < \frac{50}{8} \), it confirms that \( \frac{49}{8} \) is indeed between \( 6 \) and \( 6 \frac{1}{4} \).
