To determine which number has the lowest value among the given expressions, we need to evaluate each expression separately.

1. Evaluate [tex]\(2 - 0.8 - 0.2\)[/tex]:
[tex]\[ 2 - 0.8 = 1.2 \][/tex]
[tex]\[ 1.2 - 0.2 = 1.0 \][/tex]
So, the value of [tex]\(2 - 0.8 - 0.2\)[/tex] is [tex]\(1.0\)[/tex].

2. Evaluate [tex]\(1 + 0.2 - 0.4\)[/tex]:
[tex]\[ 1 + 0.2 = 1.2 \][/tex]
[tex]\[ 1.2 - 0.4 = 0.8 \][/tex]
So, the value of [tex]\(1 + 0.2 - 0.4\)[/tex] is [tex]\(0.8\)[/tex].

3. Evaluate [tex]\(1 - 0.5 + 0.4\)[/tex]:
[tex]\[ 1 - 0.5 = 0.5 \][/tex]
[tex]\[ 0.5 + 0.4 = 0.9 \][/tex]
So, the value of [tex]\(1 - 0.5 + 0.4\)[/tex] is [tex]\(0.9\)[/tex].

4. Evaluate [tex]\(2 - 0.3 - 0.6\)[/tex]:
[tex]\[ 2 - 0.3 = 1.7 \][/tex]
[tex]\[ 1.7 - 0.6 = 1.1 \][/tex]
So, the value of [tex]\(2 - 0.3 - 0.6\)[/tex] is [tex]\(1.1\)[/tex].

Now, let's compare the resulting values:
[tex]\[ 1.0, \quad 0.8, \quad 0.9, \quad 1.1 \][/tex]

The number with the lowest value among these is [tex]\(0.8\)[/tex].

Therefore, the expression [tex]\(1 + 0.2 - 0.4\)[/tex] has the lowest value, which is [tex]\(0.8\)[/tex].
