Answer 2

Answer:

(d)(-4/5)

(h) (-101/108)

(I) (5/6)

Step-by-step explanation:

(d) given (-7/20)+(-9/20)

lcm is 20

(-7-9/20)

therefore (-16/20)= (-4/5)

(h) given that (-7/12)+(-4/9)

lcm is 108

therefore (-63-48/108)

so answer is (-101/108)

(I) given that (1/-2)+(1/-3)

lcm is 6

therefore (3+2/6)

the answer is 5/6
