Answer:

The answer is 1 17/24

Explanation:

3 1/8 + 3/4 + (-2 1/6)

Step 1: We rationalize

25/8 + 3/4 - 13/6

Step 2: we Find the Lowest common factor (LCM) of the denominators

The LCM of 8, 4 and 6 is 2×2×2×3 = 24

Step 3: solve the factor with the LCM

(25*24/8 + 3*24/4 - 13*24/6)/24

(25*3 + 3*6 - 13*4)/24

(75 + 18 - 52)/24

= 41/24

= 1 17/24
