Math Problem: Adding Mixed Numbers

To solve the expression 2¾ - (-1½) + (-3⅚), we can follow these steps:

1. Convert Mixed Numbers to Improper Fractions: - 2¾ = 2 + ¾ = 2 + 3/4 = 11/4 - -1½ = -1 - ½ = -1 - 1/2 = -3/2 - -3⅚ = -3 - ⅚ = -3 - 6/6 = -3 - 1 = -4

2. Perform the Addition: - 2¾ - (-1½) + (-3⅚) = 11/4 - (-3/2) + (-4)

3. Simplify the Expression: - 11/4 - (-3/2) + (-4) = 11/4 + 3/2 - 4 - Convert 3/2 to an equivalent fraction with a common denominator of 4: 3/2 = 6/4 - 11/4 + 6/4 - 4 = 17/4 - 4 - Convert 4 to an equivalent fraction with a denominator of 4: 4 = 16/4 - 17/4 - 16/4 = 1/4

Solution:

2¾ - (-1½) + (-3⅚) = 1/4
