Final answer:
To simplify the expression -1.3 - 3.6 ÷ 3.6 to the nearest tenths place, divide 3.6 ÷ 3.6 to get 1, then subtract 1.3 from 1 to get -0.3, which rounds to -0.4.
Step-by-step explanation:
To simplify the expression -1.3 - 3.6 ÷ 3.6, we first divide 3.6 ÷ 3.6, which equals 1. Then, we subtract 1.3 from 1, which gives us -0.3. Since we need to round to the nearest tenths place, -0.3 rounds to -0.4.
Therefore, the simplified expression to the nearest tenths place is -0.4.
