2,56:0,128-5,6

To solve the expression \( 2.56 : 0.128 - 5.6 \), we can break it down into two parts: the division and then the subtraction.

1. Solve the division \( 2.56 : 0.128 \): \[ 2.56 \div 0.128 = 20 \]

2. Now, subtract \( 5.6 \) from the result: \[ 20 - 5.6 = 14.4 \]

So, the final result is: \[ 14.4 \]
