f) [tex]\frac{33}{20}[/tex]

i) [tex]\frac{61}{10}[/tex]

Explicación paso a paso:

f) 1 [tex]\frac{1}{4}[/tex] + [tex]\frac{2}{5}[/tex] = [tex]\frac{5}{4}[/tex] + [tex]\frac{2}{5}[/tex] = [tex]\frac{(5*5) + (4*2)}{4*5}[/tex] = [tex]\frac{25 + 8}{20}[/tex] = [tex]\frac{33}{20}[/tex]

i) 3 [tex]\frac{3}{6}[/tex] + 2 [tex]\frac{3}{5}[/tex] = [tex]\frac{21}{6}[/tex] + [tex]\frac{13}{5}[/tex] = [tex]\frac{(21*5) + (6*13)}{6*5}[/tex] = [tex]\frac{105 + 78}{30} \\[/tex] = [tex]\frac{183}{30}[/tex] = [tex]\frac{61}{10}[/tex]
