Answer 1

Ejercicio 1:

$\frac{1}{2} + (4*\frac{3}{5}) - \frac{1}{4} \\\\\frac{1}{2} + (\frac{12}{5} )-\frac{1}{4}\\\\= \frac{53}{20}$

Ejercicio 2:

$(2*\frac{2}{4} )+\frac{3}{6} +5\\\\(1)+\frac{3}{6}+5\\\\6+\frac{3}{6}\\\\=\frac{13}{2}$

Ejercicio 3:

$\frac{2}{5} +\frac{3}{2} +(\frac{3}{6} *\frac{1}{2}) +4\\\\\frac{2}{5} +\frac{3}{2} +(\frac{3}{12}) +4\\\\\frac{2}{5} +\frac{3}{2} +\frac{3}{12} +4\\\\=\frac{123}{20}$
