Answer 3

To calculate the expression 3 5/12 - (-1 1/3) + (-4 3/8), we'll perform the following steps:

Step 1: Convert mixed numbers to improper fractions: 3 5/12 = (3 * 12 + 5) / 12 = 41 / 12 -1 1/3 = (-1 * 3 + 1) / 3 = -2 / 3 -4 3/8 = (-4 * 8 + 3) / 8 = -29 / 8

Step 2: Simplify the expression: 3 5/12 - (-1 1/3) + (-4 3/8) = 41 / 12 - (-2 / 3) + (-29 / 8)

Step 3: Find a common denominator: The common denominator for 12, 3, and 8 is 24.

Step 4: Convert all fractions to have a denominator of 24: 41 / 12 = (41 * 2) / (12 * 2) = 82 / 24 -2 / 3 = (2 * -8) / (3 * -8) = -16 / 24 -29 / 8 = (29 * -3) / (8 * -3) = 87 / 24

Step 5: Perform the arithmetic: 82 / 24 - (-16 / 24) + (-29 / 8) = 82 / 24 + 16 / 24 - 87 / 24 = (82 + 16 - 87) / 24 = 11 / 24

Therefore, the value of the expression 3 5/12 - (-1 1/3) + (-4 3/8) is 11/24.
