Question

[Trần Tuấn Trọng]

Tính

6/10-4/9-16/15

Answer 1

[Nguyễn Ngọc Khánh Huyền]

\(\dfrac{6}{10}-\dfrac{4}{9}-\dfrac{16}{15}\)
 

\(=\dfrac{3}{5}-\dfrac{4}{9}-\dfrac{16}{15}\)

\(=\dfrac{27}{45}-\dfrac{20}{45}-\dfrac{48}{45}\)

\(=-\dfrac{41}{45}\)

Answer 2

[Bùi Như Quỳnh]

    \(\dfrac{6}{10}\) - \(\dfrac{4}{9}\) - \(\dfrac{16}{15}\)

=   \(\dfrac{6\times9}{10\times9}\)- \(\dfrac{4\times10}{9\times10}\) - \(\dfrac{16\times6}{15\times6}\)

= \(\dfrac{54}{90}\) - \(\dfrac{40}{90}\) - \(\dfrac{96}{90}\)

= \(\dfrac{-82}{90}\)

= \(\dfrac{-41}{45}\)
