Answer 3

To simplify the expression, combine like terms and perform the necessary arithmetic operations:

2/5a - b - a - 6/10b

First, combine the "a" terms: 2/5a - a = (2/5 - 1)a = (2/5 - 5/5)a = (-3/5)a

Now, combine the "b" terms: -b - 6/10b = (-1 - 6/10)b = (-10/10 - 6/10)b = (-16/10)b = (-8/5)b

So, the simplified expression is:

(-3/5)a - (8/5)b

Alternatively, you can factor out the common terms "a" and "b" to get:

a(-3/5) - b(8/5)

Both representations are correct, and it depends on the context and specific requirements of the problem which form is more suitable.
