Answer:
+37/144
Step-by-step explanation:
(3/8 x -5/4) ÷ (1/3 x 5/6) + (-1/2 - 1/5) x (-5/7 x 5/8)
(-15/32) ÷ (5/18) + (-7/10) x (-25/56)
Reciprocal
(-15/32) x (18/5) + (-7/10) x (-25/56)
(-27/16) + (+175/560)
Bring then to the lowest terms
(-27/16) + (+35/18)
Take LCM and Add then up
LCM = 144
-243 + 280
144
+37/144 is the final answer
