5,17 : ( -1,3) + 1,43 x 1,1 + 39 x 0,143 + 7, 83 :( -1,3)

Answer 1

`5,17 : ( -1,3) + 1,43. 1,1 + 39. 0,143 + 7,83 : (-1,3)`

`=5,17  .(-10)/(13) + 7,83 .(-10)/13 +0,143.11 + 39. 0,143 `

`= (-10)/13 .( 5,17+7,83) + 0,143.(11+39)`

`= -10 + 7,15`

`=-2,85`

Answer 2

5,17:(−1,3)+1,43.1,1+39.0,143+7,83:(−1,3)=(5,17+7,83):(−1,3)+1,43.1,1+1,43.3,9=(5,17+7,83):(−1,3)+1,43(1,1+3,9)=13:(−1,3)+1,43.5=−10+7,15=−2,85
