Answer 1

[ღŤ.Ť.Đღ]

\(\frac{5}{6}\times\frac{7}{12}+\frac{5}{12}\times\frac{5}{6}+\frac{1}{6}\) 

= \(\frac{35}{72}+\frac{25}{36}+\frac{1}{6}\)

= \(\frac{97}{72}\)

\(\left(\frac{8}{15}\times\frac{3}{4}\times\frac{5}{4}\right):\frac{7}{8}\)

= \(\frac{1}{2}:\frac{7}{8}\)

=\(\frac{4}{7}\)

HOK TỐT ^^
