Question

 

\(\left(10\dfrac{2}{9}+2\dfrac{3}{5}\right)-6\dfrac{2}{9}\)

Answer 1

`(10 2/9 + 2 3/5) - 6 2/9`

`=10 2/9 + 2 3/5 - 6 2/9`

`=[10 2/9 - 6 2/9] + 2 3/5`

`=[ (10-6)(2/9-2/9)]+2 3/5`

`=4 + 2 3/5`

`=(4+2)+3/5`

`=6 3/5`

`=33/5`

Answer 2

\(=10+\dfrac{2}{9}+2+\dfrac{3}{5}-6-\dfrac{2}{9}\)

=6+3/5

=6,6
