We want to divide two decimal numbers.
- 3.45Ă· (- 15)
First, recall that when dividing real numbers, the quotient will be positive if the signs are the same and it will be negative if the signs are different.

Same Sign & Different Signs
(+)Ă· (+)=(+) & (+)Ă· (-)=(-)
(-)Ă· (-)=(+) & (-)Ă· (+)=(-)
In our case both numbers are negative, so the quotient will be positive.
- 3.45Ă· (- 15)=3.45Ă· 15
Let's find the quotient! We will divide, multiply, subtract, and compare as many times as we need.
Since 3.45Ă· 15=0.23, we know that - 3.45Ă· (- 15)=0.23.
