Question

9,15:0,5+9,15x9-9,15

Answer 1

`9,15:0,5+9,15xx9-9,15`

`=9,15xx2+9,15xx9-9,15xx1`

`= 9,15 xx (2+9-1)`

`= 9,15 xx 10`

`=91,5`

Answer 2

9,15 : 0,5 + 9,15 x 9 - 9,15

\(=9,15:\dfrac{1}{2}+9,15\times9-9,15\times1\)

\(=9,15\times2+9,15\times9-9,15\times1\)

= 9,15 x (2+9-1)

= 9,15 x 10

= 91,5

Answer 3

\(9,15:0,5+9,15\times9-9,15\)

\(=9,15\times\dfrac{10}{5}+9,15\times9-9,15\times1\)

\(=9,15\times2+9,15\times9-9,15\times1\)

\(=9,15\times\left(2+9-1\right)\)

\(=9,15\times10\)

\(=91,5\)
