Is it [ -(–0.4) ] or (-0.4) did you solve it both ways if it was [–(–0.4) ] or (-0.4)
____o______o____
[tex]0.2 \div - 1 \times (0.6 - 0.4) \\ = - 0.2 \times (0.2) \\ = - 0.04[/tex]
_____o_____o_____
[tex]0.2 \div - 1 \times (0.6 - ( - 0.4)) \\ = - 0.2 \times (0.6 + 0.4) \\ = - 0.2(1) \\ = - 0.2[/tex]
I hope I helped you^_^
