Answer:
-37/168
Step-by-step explanation:
(-7/12 x 3/-14 + 4/-9) / (1/3)
= (-7/12 x (-3/14) + (-4/9)) / (1/3)
= (-21/168 + (-4/9)) / (1/3)
= L.C.M. of 168 and 9 is 504
=> (-21 x 3/168 x 3) = (-63/504)
=> (-4 x 56/9 x 56) = (-244/504)
= ((-63 + (-244))/504) / (1/3)
= (-307/504) / (1/3)
= (-307/504) x 3
= (-921/504)
= -37/168
