what is −6 7/12 − 4 1/3?

To subtract mixed numbers, we first need to convert them to improper fractions.

Converting -6 7/12 to an improper fraction:
-6 is equivalent to -6/1
Multiplying the whole number (-6) by the denominator (12) and adding the numerator (7), we get -6*12 + 7 = -72 + 7 = -65.
Therefore, -6 7/12 is equivalent to -65/12.

Converting 4 1/3 to an improper fraction:
4 is equivalent to 4/1
Multiplying the whole number (4) by the denominator (3) and adding the numerator (1), we get 4*3 + 1 = 12 + 1 = 13.
Therefore, 4 1/3 is equivalent to 13/3.

Now we can subtract the two fractions:
-65/12 - 13/3

To find a common denominator, we need to find the least common multiple (LCM) of 12 and 3, which is 12.

Now we can rewrite the fractions with the common denominator of 12:
(-65/12) - (13/3) = (-65/12) - (52/12)

By subtracting the numerators and keeping the common denominator:
= (-65 - 52)/12 = -117/12.

So, -6 7/12 - 4 1/3 is equal to -117/12.
