Let's simplify the expression step by step:

The expression is:

\[ -4.08 \div 1.2 - (-4.2) \times 1.5 \]

  1. Calculate \(-4.08 \div 1.2\): \[ -4.08 \div 1.2 = -3.4 \]

  2. Calculate \((-4.2) \times 1.5\): \[ -4.2 \times 1.5 = -6.3 \]

    Now, since we're subtracting a negative, this will turn into addition: \[

    • (-6.3) = +6.3 \]

  3. Combine the results: \[ -3.4 + 6.3 = 2.9 \]

So, the simplified expression is:

\[ \boxed{2.9} \]
