{\dfrac{2}{5}m-\dfrac{4}5-\dfrac{3}5m}

Answer 1

To evaluate this expression, we first combine the like terms:

2/5m - 3/5m = (2/5 - 3/5)m = (-1/5)m

Then we can simplify further by adding the constant terms:

-1/5m - 4/5 = -1/5m - 4/5 = -1/5 - 4/5 = -5/5 = -1

Therefore, the simplified expression is:

-1.
