So first thing we have to realise is that we have to make them have equal denominators. So,
[tex] \frac{1}{6} = \frac{4}{24} \\ \\ \frac{1}{8} = \frac{3}{24} \\ \\ \frac{1}{3} = \frac{8}{24} [/tex].
Now order the fractions....so,
[tex]\frac{1}{3} = \frac{8}{24} \\ \\ \frac{1}{6} = \frac{4}{24} \\ \\ \frac{1}{8} = \frac{3}{24} [/tex]
Now we can see why [tex] \frac{1}{6} [/tex] is greater than [tex] \frac{1}{8} [/tex] but less than [tex] \frac{1}{3} [/tex]
