2. [tex]\frac{8}{10}-\frac{1}{5}[/tex] Make the denominators the same in order to subtract them (bottom of the fraction)
[tex]\frac{8}{10}-\frac{2}{10}[/tex]
[tex]\frac{6}{10}[/tex] Simplify
[tex]\frac{3}{5}[/tex]
3. [tex]\frac{7}{12}-\frac{1}{4}[/tex] Make the denominators the same
[tex]\frac{7}{12}-\frac{3}{12}[/tex]
[tex]\frac{4}{12}[/tex] Simplify
[tex]\frac{1}{3}[/tex]
4. "Difference" is subtraction, so:
[tex]\frac{7}{8}-\frac{1}{4}[/tex]
[tex]\frac{7}{8}-\frac{2}{8}[/tex]
[tex]\frac{5}{8}[/tex]
5. [tex]\frac{7}{12} -\frac{1}{3}[/tex]
[tex]\frac{7}{12}-\frac{4}{12}=\frac{3}{12}=\frac{1}{4}[/tex]
Continue doing that for the rest of the problems
