Answer 2

To calculate the expression, we need to perform subtraction and addition of mixed numbers. Let's break it down step-by-step:

Step 1: Convert all the mixed numbers to improper fractions. Step 2: Perform the subtraction and addition. Step 3: Convert the result back to a mixed number if necessary.

Given expression: 4 2/3 - (3 3/4) + (-2 5/6) - 5 1/8

Step 1: 4 2/3 = (34 + 2)/3 = 14/3 3 3/4 = (43 + 3)/4 = 15/4 -2 5/6 = -(62 + 5)/6 = -17/6 5 1/8 = (85 + 1)/8 = 41/8

Step 2: Now, perform the subtraction and addition: 14/3 - 15/4 + (-17/6) - 41/8

Step 3: To add and subtract fractions, we need to find a common denominator, which is the least common multiple (LCM) of 3, 4, 6, and 8. LCM(3, 4, 6, 8) = 24.

Now, we'll rewrite each fraction with a denominator of 24: (14/3) * (8/8) = 112/24 (15/4) * (6/6) = 90/24 (-17/6) * (4/4) = -68/24 (41/8) * (3/3) = 123/24

Now, the expression becomes: (112/24) - (90/24) - (68/24) - (123/24)

Combine the fractions: (112 - 90 - 68 - 123)/24 = (-169)/24

Now, the result is a negative improper fraction. Let's convert it back to a mixed number: Divide the numerator (-169) by the denominator (24): -169 ÷ 24 = -7 with a remainder of 7

So, the result is: -7 7/24
