Answer:
Step-by-step explanation: Since both the numerator and the denominator have a minus (-), they even each other out and the minus signs can be removed. Then we are left with this:
13
23
Now that both the dividend and divisor are positive numbers, we can simply divide 13 by 23 as follows:
13 ÷ 23 = 0.565217391304348
Which means that this is the answer to "What is negative 13 divided by negative 23?":
(-13) ÷ (-23) = 0.565217391304348
