Answer:
4/9 in the simplest form
Explanation:
When dividing by a negative number the sign of the quotient changes. so if the quotient is negative when the divisor and dividend have the same sign, it becomes positive when they have opposite sign. In this case -12 and -25 have opposite signs and the quotient will be positive, that's why the negative signs cancel out.
-12 / (-25) = 12/25 = 4/9 in the simplest form
