Completa las siguientes operaciones

Answer 1

Respuesta:

a) $\frac{3}{5}+\frac{1}{5}=\frac{3+1}{5}=\frac{4}{5}$

b) $\frac{1}{3}+\frac{1}{4}=\frac{4}{12}+\frac{3}{12}=\frac{7}{12}$

c) $\frac{1}{2}+\frac{1}{4}=\frac{3}{4}$

d) $\frac{1}{2}+\frac{2}{3}=\frac{7}{6}$

e) $\frac{2}{5}+\frac{3}{7}=\frac{29}{35}\quad$

f) $5\frac{3}{4}+2\frac{3}{5}=7+\frac{27}{20}=7+1\frac{7}{20}=8\frac{7}{20}$

g) $\frac{6}{7}-\frac{6}{9}=\frac{6}{7}-\frac{2}{3}=\frac{18}{21}-\frac{14}{21}=\frac{18-14}{21}=\frac{4}{21}$

h) $3\frac{1}{2}-1\frac{2}{3}=2\frac{3}{2}-1\frac{2}{3}=1+\frac{5}{6}=1\frac{5}{6}$
