2,48+0.4×(-1,6)

To solve the expression \( 2.48 + 0.4 \times (-1.6) \), we follow the order of operations:

1. First, multiply \( 0.4 \) by \( -1.6 \): \[ 0.4 \times -1.6 = -0.64 \]

2. Now, substitute this result back into the expression: \[ 2.48 + (-0.64) \]

3. This can be simplified by subtracting \( 0.64 \) from \( 2.48 \): \[ 2.48 - 0.64 = 1.84 \]

Therefore, the final answer is \( 1.84 \).
