How is this even solved? I need a step-by-step or an answer. Please and thank you.
Do the LHS first: (5/8) / -(5/9) =(5/8) x -(9/5) =(5 x -9) / (8 x 5) =-45 / 40.
Now, do the RHS: n / (8 / 15) =n x (15 / 8) = 15n / 8
Now, put the LHS and the RHS together:
-45/40 = 15n/8 Cross multiply
-45 x 8 =15n x 40
-360 = 15n x 40 Divide both sides by 15 x 40 =600
-360/600 = n
n = -0.6
