To arrange the given fractions in ascending order, we will follow these steps:
### Part (i): Arrange `7/8`, `15/6`, `5/6`
1. **Identify the fractions**: The fractions we need to arrange are \( \frac{7}{8}, \frac{15}{6}, \frac{5}{6} \).
2. **Find the LCM of the denominators**: The denominators are 8 and 6. The LCM of 8 and 6 is 24.
3. **Convert each fraction to have a common denominator**:
- For \( \frac{7}{8} \):
\[
\frac{7}{8} = \frac{7 \times 3}{8 \times 3} = \frac{21}{24}
\]
- For \( \frac{15}{6} \):
\[
\frac{15}{6} = \frac{15 \times 4}{6 \times 4} = \frac{60}{24}
\]
- For \( \frac{5}{6} \):
\[
\frac{5}{6} = \frac{5 \times 4}{6 \times 4} = \frac{20}{24}
\]
4. **Compare the numerators**: Now we have the fractions \( \frac{21}{24}, \frac{60}{24}, \frac{20}{24} \). The numerators are 21, 60, and 20.
- The smallest numerator is 20, so \( \frac{5}{6} \) is the smallest fraction.
- Next is 21, so \( \frac{7}{8} \) is the second.
- Lastly, 60 corresponds to \( \frac{15}{6} \).
5. **Arrange in ascending order**: Thus, the fractions in ascending order are:
\[
\frac{5}{6}, \frac{7}{8}, \frac{15}{6}
\]
### Part (ii): Arrange `3/4`, `15/22`, `26/33`
1. **Identify the fractions**: The fractions we need to arrange are \( \frac{3}{4}, \frac{15}{22}, \frac{26}{33} \).
2. **Find the LCM of the denominators**: The denominators are 4, 22, and 33. The LCM of 4, 22, and 33 is 132.
3. **Convert each fraction to have a common denominator**:
- For \( \frac{3}{4} \):
\[
\frac{3}{4} = \frac{3 \times 33}{4 \times 33} = \frac{99}{132}
\]
- For \( \frac{15}{22} \):
\[
\frac{15}{22} = \frac{15 \times 6}{22 \times 6} = \frac{90}{132}
\]
- For \( \frac{26}{33} \):
\[
\frac{26}{33} = \frac{26 \times 4}{33 \times 4} = \frac{104}{132}
\]
4. **Compare the numerators**: Now we have the fractions \( \frac{99}{132}, \frac{90}{132}, \frac{104}{132} \). The numerators are 99, 90, and 104.
- The smallest numerator is 90, so \( \frac{15}{22} \) is the smallest fraction.
- Next is 99, so \( \frac{3}{4} \) is the second.
- Lastly, 104 corresponds to \( \frac{26}{33} \).
5. **Arrange in ascending order**: Thus, the fractions in ascending order are:
\[
\frac{15}{22}, \frac{3}{4}, \frac{26}{33}
\]
### Final Answer:
- For part (i): \( \frac{5}{6}, \frac{7}{8}, \frac{15}{6} \)
- For part (ii): \( \frac{15}{22}, \frac{3}{4}, \frac{26}{33} \)
