Answer 1

`@` `\text {Ans}`

`\downarrow`

`2/5 - 8/9 * -27/40`

`= 2/5 - (-3/5)`

`= 2/5 +3/5`

`= 1`

Answer 2

\(\dfrac{2}{5}-\dfrac{8}{9}\cdot\dfrac{-27}{40}\)

\(=\dfrac{2}{5}-\left(-\dfrac{216}{360}\right)\)

\(=\dfrac{2}{5}+\dfrac{216}{360}\)

\(=\dfrac{2}{5}+\dfrac{3}{5}\)

\(=\dfrac{5}{5}=1\)
