2 [tex] \frac{3}{8} [/tex] = [tex] \frac{2(8)+3}{8} = \frac{19}{8} [/tex]
5 [tex] \frac{3}{4} = \frac{5(4)+3}{4} = \frac{23}{4} [/tex]
[tex] \frac{19}{8} [/tex]÷[tex] \frac{23}{4} [/tex]
= [tex] \frac{19}{8}[/tex] x [tex] \frac{4}{23} [/tex]
= [tex] \frac{19(4)}{8(23)} [/tex]
= [tex] \frac{19}{2(23)} [/tex]
