We have the following general rule for the substraction of fractions:
[tex]\begin{gathered} \frac{a}{b}-\frac{c}{d}=\frac{a\cdot d-b\cdot c}{b\cdot d} \\ b,d\ne0 \end{gathered}[/tex]then, in this case we have the following:
[tex]\frac{8}{10}-\frac{2}{6}=\frac{8\cdot6-10\cdot2}{10\cdot6}=\frac{48-20}{60}=\frac{28}{60}[/tex]simplifying, we get:
[tex]\frac{28}{60}=\frac{7}{15}[/tex]therefore, the result of the substraction is 7/15
