Answer:
[tex]1\displaystyle\frac{1}{4}[/tex]
Step-by-step explanation:
1. Change into improper fractions
[tex]3\displaystyle\frac{1}{8}[/tex] → [tex]\displaystyle\frac{25}{8}[/tex]
[tex]1\displaystyle\frac{7}{8}[/tex] → [tex]\displaystyle\frac{15}{8}[/tex]
2. Subtract the fractions
[tex]\displaystyle\frac{25}{8}[/tex] - [tex]\displaystyle\frac{15}{8}[/tex] = [tex]\displaystyle\frac{10}{8}[/tex]
3. Simplify
[tex]\displaystyle\frac{10}{8}[/tex] → [tex]\displaystyle\frac{5}{4}[/tex]
4. Write as a mixed number
[tex]\displaystyle\frac{5}{4}[/tex] → [tex]1\displaystyle\frac{1}{4}[/tex]
