Evaluate the given expression.

Question

0.4-0.2+0.8+(-0.8

A.
-0.6
B.
0.6
C.
0.2
D.
-0.2

Answer 1

To evaluate the expression \(0.4 - 0.2 + 0.8 + (-0.8)\), follow these steps:

1. Calculate \(0.4 - 0.2\): \[ 0.4 - 0.2 = 0.2 \]

2. Add \(0.8\) to the result: \[ 0.2 + 0.8 = 1.0 \]

3. Now, add \(-0.8\) to that result: \[ 1.0 + (-0.8) = 1.0 - 0.8 = 0.2 \]

Thus, the value of the expression is \(0.2\).

The answer is C. 0.2.
