[2/5 - (-0,4) : (-0,12)] : [4 - (-44)] =
[2/5 - 3, (3)] : [4 + 44] =
[2/5 - 3 i 1/3] : 48 =
[2/5 - 10/3] : 48 =
[6/15 - 50/15] : 48 =
-54/15 : 48/1 =
-18/5 : 48/1 =
-18/5 x 1/48 =
-18/240 =
-0,075 = 3/40 (możesz wynik zapisać to na obydwa sposoby)

[2/5-(-2/5):(-6/5)]:48=[2/5-(-2/5)*(-5/6):48=[2/5-3]:48=-23/5:48=13/5*1/48=13/240
