To find the quotient of \( 842.4 \div -0.6 \), you can perform the division as follows:
- Divide the absolute values: \( 842.4 \div 0.6 \).
Calculating that:
\[ 842.4 \div 0.6 = 1404 \]
- Since you're dividing by a negative number (\(-0.6\)), the quotient will also be negative.
Thus,
\[ 842.4 \div -0.6 = -1404 \]
So, the correct answer is:
\(-1,404\)
