Hola es queno puedo con mi tarea nose como hacelo ayydenme porfaaa

Answer 1

Hola.

$\frac{3}{8}+ \frac{1}{6} \\ \\ mcm = 24 \\ \\ \frac{3*3}{24}+ \frac{4}{24} \\ \\ \frac{3\cdot \:3+4}{24} \\ \\ \boxed{R1: \frac{13}{24}}$

-------------------------------------------------------------------------------------------------------

$\frac{1}{6}+\frac{2}{9} \\ \\ mcm = 18 \\ \\ \frac{3+2\cdot \:2}{18} \\ \\ \boxed{R2: \ \frac{7}{18}}$

-------------------------------------------------------------------------------------------------------

$\frac{3}{4}+\frac{1}{6} \\ \\ mcm = 12 \\ \\ \frac{3\cdot \:3+2}{12} \\ \\ \boxed{R3: \frac{11}{12}}$

-------------------------------------------------------------------------------------------------------

$\frac{1}{3}+\frac{1}{4} \\ \\ mcm = 12 \\ \\ \frac{4+3}{12} \\ \\ \boxed{R4: \ \frac{7}{12}}$

-------------------------------------------------------------------------------------------------------

$\frac{1}{2}+\frac{2}{5} \\ \\ Mcm = 10 \\ \\ \frac{5+2\cdot \:2}{10} \\ \\ \boxed{R5: \frac{9}{10}}$

-------------------------------------------------------------------------------------------------------

$\frac{1}{3}+\frac{3}{5} \\ \\ Mcm = 15 \\ \\ \frac{5+3\cdot \:3}{15} \\ \\ \boxed{R6: \frac{14}{15}}$

-------------------------------------------------------------------------------------------------------

$\frac{3}{4}+\frac{1}{5} \\ \\ Mcm = 20 \\ \\ \frac{3\cdot \:5+4}{20} \\ \\ \boxed{R7: \frac{19}{20}}$

¡Espero haberte ayudado, saludos... G.G.H!
