The simplified solutions are:

1. 5/6 + 1/3 = 3/2

2. 7/4 - 2/5 = 19/20

3. 3/8 + 2/3 - 5/24 = 3/1

Let's evaluate the expressions one by one:

1. 5/6 + 1/3

Adding the fractions with the least common denominator of 6, we get:

(5 * 1) / (6 * 1) + (2 * 2) / (6 * 2) = 5/6 + 4/6 = 9/6

Simplifying the fraction, we get:

9/6 = 3/2

2. 7/4 - 2/5

Finding a common denominator for 4 and 5, we get 20:

(7 * 5) / (4 * 5) - (4 * 4) / (5 * 4) = 35/20 - 16/20 = 19/20

3. 3/8 + 2/3 - 5/24

First, let's find a common denominator for 8, 3, and 24:

(3 * 3) / (8 * 3) + (8 * 8) / (3 * 8) - (1 * 1) / (24 * 1) = 9/24 + 64/24 - 1/24 = 72/24

Simplifying the fraction, we get:

72/24 = 3/1

Question:

Compute the following operations with rational numbers:

1. 5/6 + 1/3

2. 7/4 - 2/5

3. 3/8 + 2/3 - 5/24

Perform addition and subtraction for each pair of rational numbers, simplifying the results where possible.
