1. 2 divide by 2/3+ 3 divide by 4 divide by 4/5=
2. If 2/5 of 2/3 divide by 5/6 is divided by 3/10, what is the resulting value?

1. Do you mean?
2/(2/3) + (3/4) / (4/5) =
2*(3/2 + (3/4)(5/4) =
3 + 15/16 = 3 15/16.
2. (((2/5)*(2/3)) / (5/6)) / (3/10) =
((4/15) / (5/6)) / (3/10) =
(4/15)*(6/5) / (3/10) =
(24/75) * (10/3) = (8/15)*(2/1) = 16/15=
1 1/15.
