just use the traditional way to add fractions ...
-1/6 + (-3/7)
= -7/42 - 18/42
= -25/42
To find the sum of -1/6 and -3/7, you need to add the two fractions together. Here's how you can do it:
Step 1: Find a common denominator for the fractions (-1/6 and -3/7). To do this, you need to find the least common multiple (LCM) of the denominators, which in this case are 6 and 7.
The LCM of 6 and 7 is 42.
Step 2: Rewrite the fractions with the common denominator of 42.
-1/6 can be written as -7/42 (by multiplying the numerator and denominator by 7).
-3/7 can be written as -18/42 (by multiplying the numerator and denominator by 6).
Step 3: Add the numerators together and keep the common denominator.
(-7/42) + (-18/42) = (-7 - 18)/42 = -25/42
So, the sum of -1/6 and -3/7 is -25/42.
Therefore, the correct answer is option D, 2/13, is incorrect as the sum is -25/42.
