We must substract 3 1/6 of 4 2/3. However, we must convert these fractions in
mixed form to simple fraction:
[tex]3\frac{1}{6}=\frac{6\cdot3+1}{6}=\frac{19}{6}[/tex]and
[tex]4\frac{2}{3}=\frac{3\cdot4+2}{3}=\frac{14}{3}[/tex]hence,
[tex]4\frac{2}{3}-3\frac{1}{6}=\frac{14}{3}-\frac{19}{6}[/tex]therefore,
[tex]\begin{gathered} \frac{14}{3}-\frac{19}{6}=\frac{6\cdot14-3\cdot19}{3\cdot6} \\ \frac{14}{3}-\frac{19}{6}=\frac{84-57}{18} \\ \frac{14}{3}-\frac{19}{6}=\frac{27}{18} \\ \frac{14}{3}-\frac{19}{6}=\frac{3}{2} \end{gathered}[/tex]Maria has 3/2=1.5 left over
