Instructions: Tell whether each expression represents a positive number or a negative number when m and n are negative.
problem: -n/-m
If both m and n are negative, then both -m and -n (numerator and denominator) are positive. What does that tell you about the fraction?
To determine whether the expression "-n/-m" represents a positive or negative number when both m and n are negative, we need to understand the behavior of negative numbers in fractions.
When both m and n are negative, it means that -m and -n are positive numbers. In a fraction, if both the numerator and the denominator have the same sign (in this case, positive), the fraction itself will always be positive.
So, when m and n are negative, the expression "-n/-m" represents a positive number.
