Given:-1/6 + -3/7
Find LCD: -7/42 + -18/42
Combine like terms: -7/42 - 18/42 = -25/42
Therefore, your answer is -25/42, or, as a decimal, what @puppybowl answered.

To add fractions together, you need to have a common denominator. The common denominator is the smallest number that both denominators divide into evenly. In this case, the denominators are 6 and 7, so the common denominator is 6 * 7 = 42.
To convert the fractions to have a common denominator, you need to multiply the numerator and the denominator of each fraction by the same number so that the denominator becomes 42.
For -1/6, you would multiply both the numerator and denominator by 7, since 6 * 7 = 42. This gives you (-1 * 7) / (6 * 7) = -7/42.
For -3/7, you would multiply both the numerator and denominator by 6, since 7 * 6 = 42. This gives you (-3 * 6) / (7 * 6) = -18/42.
Now that both fractions have a common denominator of 42, you can add them together:
-7/42 + (-18/42)
To add fractions with the same denominator, you simply add the numerators and keep the denominator the same:
= (-7 - 18) / 42
= -25/42
So, -1/6 + (-3/7) is equal to -25/42.
