For the first one, we calculate the sum of the fractions in the parentheses first.
1/2 + 1/3 = 5/6.
Now, we multiply the 5/6 by 2/5, and we get 10/30, which simplifies to 1/3.
For the second one, the order of operations tells us to do the division first.
(11/10)/(22/5)
= 11/10 * 5/22
= 1/4.
Now, we subtract 1/4 from 5/6.
5/6 - 1/4
= 14/24
= 7/12.
