[tex]precio \: sombrero = 2 \frac{3}{5} = \frac{13}{5} [/tex]
[tex]precio \: camisa = 3 \frac{3}{4} = \frac{15}{4} [/tex]
Compro 3 sombreros, entonces:
[tex]3 \times \frac{13}{5} = \frac{39}{5} [/tex]
Compro 6 camisas, entonces:
[tex]6 \times \frac{15}{4} = \frac{45}{2} [/tex]
CALCULANDO CUANTO LE DEVUELVEN:
[tex]50 - ( \frac{39}{5} + \frac{45}{2} )[/tex]
[tex]50 - ( \frac{78 + 225}{10} )[/tex]
[tex]50 - \frac{303}{10} [/tex]
[tex] \frac{500 - 303}{10} [/tex]
[tex] \frac{197}{10} [/tex]
[tex]19 \frac{7}{10} [/tex]
