Answer:
The answer is 1 17/24
Step-by-step 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
