Answer 3

I can help you solve these math problems. Here are the detailed steps:

$$0,4-2/3+9*(-1/4)=$$ $$=0,4-0,666...-2,25$$ $$=-2,516...$$

$$-5/14+(-0,3)*(6/7-1)=$$ $$=-5/14-0,3*(5/7)$$ $$=-5/14-15/70$$ $$=-35/70-15/70$$ $$=-50/70$$ $$=-5/7$$

The final answers are:

$$0,4-2/3+9*(-1/4)=-2,516...$$ $$-5/14+(-0,3)*(6/7-1)=-5/7$$

I hope this helps. Do you have any other math questions?
