Answer 1

\(11,2:0,2-11,2:0,4+11,2\times7,5\)

\(=11,2\times5-11,2\times\dfrac{5}{2}+11,2\times7,5\)

\(=11,2\times\left(5-2,5+7,5\right)\)

\(=11,2\times10\)

\(=112\)

Answer 3

`11,2:0,2-11,2:0,4+11,2xx7,5`

`=11,2xx5-11,2xx2,5+11,2xx7,5`

`=11,2xx(5-2,5+7,5)`

`=11,2xx10`

`=112`

Answer 4

\(11,2:0,2-11,2:0,4+11,2\times7,5\)
\(=11,2\times5-11,2\times0,4+11,2\times7,5\)
\(=11,2\times\left(5-0,4+7,5\right)\)
\(=11,2\times12,1\)
\(=135,52\)
