To find the sum of -1/9 and -5/7, you need to add the two fractions together. Here's how you can do that:
Step 1: Find a common denominator for the two fractions. In this case, the least common denominator (LCD) is 63 because 9 and 7 are relatively prime.
Step 2: Convert both fractions into fractions with the LCD as their denominator:
-1/9 = -7/63 (multiply numerator and denominator by 7)
-5/7 = -45/63 (multiply numerator and denominator by 9)
Step 3: Add the two fractions together:
(-7/63) + (-45/63) = (-7 - 45)/63 = -52/63
So, the correct answer is B. -52/63.
Your answer, C. -6/7, is incorrect. Please recheck your calculations.
