-1/6 + (-3/7)
-7/42 - 18/42
-25/42
To solve the equation -1/6 + (-3/7), we need to find a common denominator.
First, let's find the common denominator of 6 and 7. The smallest number that both 6 and 7 divide into evenly is 42.
Next, we'll convert -1/6 and -3/7 into fractions with the common denominator of 42.
-1/6 = -7/42 (Multiply the numerator and denominator by 7)
-3/7 = -18/42 (Multiply the numerator and denominator by 6)
Now that both fractions have a common denominator of 42, we can add them:
-7/42 + (-18/42) = -25/42
Therefore, the answer is A. -25/42.
To add fractions with different denominators, you'll need to find a common denominator. In this case, the common denominator is the lowest common multiple (LCM) of 6 and 7, which is 42.
Now, let's rewrite the fractions with the common denominator:
-1/6 can be rewritten as (-1/6) * (7/7) = -7/42
-3/7 can be rewritten as (-3/7) * (6/6) = -18/42
Now, simply add the numerators:
(-7/42) + (-18/42) = -25/42
So, the answer is A) -25/42.
