To find the difference between the amount she had yesterday and amount she has today, set it up like this:
[tex] \frac{5}{6} - \frac{2}{3} [/tex]
Since the terms aren't compatible, we need to convert [tex] \frac{2}{3} [/tex] into a fraction with a common denominator:
[tex]\frac{5}{6} - \frac{2}{3}( \frac{2}{2} )= \frac{5}{6} - \frac{4}{6}[/tex]
The terms can now be subtracted:
[tex]\frac{5}{6} - \frac{4}{6} = \frac{1}{6} [/tex]
Ruby had [tex] \frac{1}{6} [/tex] pounds more cinnamon yesterday.
