[Aikatsu mizuki]

Tính bằng cách thuận tiện ;

\(\frac{5}{6}\)\(\div\)\(\frac{8}{9}\)\(-\)\(\frac{3}{4}\)\(\div\)\(\frac{8}{9}\)

Answer 1

[Con gái không phải dạng vừa đâu]

\(\frac{5}{6}:\frac{8}{9}-\frac{3}{4}:\frac{8}{9}\)

\(=\left(\frac{5}{6}-\frac{3}{4}\right):\frac{8}{9}\)

\(=\frac{1}{12}:\frac{8}{9}\)

\(=\frac{1}{12}\times\frac{9}{8}\)

\(=\frac{3}{32}\)

Answer 2

[Tobiichi Origami]

(\(\frac{5}{6}\)-\(\frac{3}{4}\)) : \(\frac{8}{9}\)

=\(\frac{1}{12}\): \(\frac{8}{9}\)

=\(\frac{3}{32}\)
