Answer:
La respuesta es c
Step-by-step explanation:
Answer:
I. 1/5
II. -1/14
III. 2/9
Step-by-step explanation:
(i) (-3/5) + (-2/7)
Opening up the bracket;
3/5 - 2/5 =
Lowest common multiple (LCM) = 5
(3 - 2)/5
= 1/5
(ii) (-2/7) - (-3/14)
Opening up the bracket;
-2/7 + 3/14 =
Lowest common multiple (LCM) = 14
(-4 + 3)/14 = -1/14
(iii) (-4/ 9) = (- 2/3)
Rearranging the fraction, we have;
-4/9 + 2/3 =
Lowest common multiple (LCM) = 9
(-4 + 6)/9 = 2/9
