add -8/13 + 4/15 (1 point)
answers:
4/15 A
-12/15 B
4/5 C
-4/15 D
To solve this problem, we need to find a common denominator for the fractions -8/13 and 4/15.
The common denominator for 13 and 15 is 195, so we can rewrite the fractions as:
-8/13 = -8 * (15/15) / 13 = -120/195
4/15 = 4 * (13/13) / 15 = 52/195
Now we can add the fractions:
-120/195 + 52/195 = (-120 + 52)/195 = -68/195
Therefore, the answer is -68/195, which is equivalent to -4/15.
D. -4/15
To add -8/13 and 4/15, we need to find a common denominator.
The least common multiple (LCM) of 13 and 15 is 195.
Converting the fractions to have a denominator of 195:
-8/13 = -8/13 * 15/15 = -120/195
4/15 = 4/15 * 13/13 = 52/195
Adding the fractions:
-120/195 + 52/195 = (-120 + 52)/195 = -68/195
Therefore, the answer is -68/195.
