Solution

-2/3*3/5 + 5/2 - 3/5*1/6

First, use the cummutative (and associative) properties of addition and multiplication to change the order:

5/2 - 3/5*2/3 - 3/5*1/6

and then use the distributive law to factor out -3/5:

5/2 - (3/5)*(2/3 + 1/6)

Common denominator and add, then reduce, and the rest is simple:

5/2 - (3/5)*(4/6 + 1/6) = 5/2 - 3/5*5/6 = 5/2 - 3/6 = 5/2 - 1/2 = 4/2 = 2
