Cách 1:
($\frac{2}{3}$ + $\frac{1}{4}$) x $\frac{3}{2}$
= ($\frac{8}{12}$ + $\frac{3}{12}$) x $\frac{3}{2}$
= $\frac{11}{12}$ x $\frac{3}{2}$
= $\frac{11}{8}$
Cách 2:
($\frac{2}{3}$ + $\frac{1}{4}$) x $\frac{3}{2}$
= $\frac{2}{3}$ x $\frac{3}{2}$ + $\frac{1}{4}$ x $\frac{3}{2}$
= 1 + $\frac{3}{8}$
= $\frac{11}{8}$
