Answer 1

3/2-(3/4-5/6)+(-2 7/12)= 3/2-(-1/12)-2 7/12= 3/2+1/12-31/12=3/2+ -30/12= 3/2+ -5/2= 3-5/2= -2/2= -1

Answer 3

To simplify the expression 3/2 - (3/4 - 5/6) + (-2 7/12), we'll break it down into smaller steps:

Step 1: Simplify the innermost parentheses.

3/2 - (3/4 - 5/6) + (-2 7/12) = 3/2 - (3/4 - 5/6) + (-2 - 7/12) [Convert mixed number to improper fraction] = 3/2 - (3/4 - 5/6) - (24/12 + 7/12) [Find a common denominator for subtraction] = 3/2 - (3/4 - 5/6) - 31/12

Step 2: Simplify the subtraction inside the parentheses.

3/2 - (3/4 - 5/6) - 31/12 = 3/2 - (9/12 - 10/12) - 31/12 [Find a common denominator for subtraction] = 3/2 - (-1/12) - 31/12 = 3/2 + 1/12 - 31/12 [Change the subtraction to addition of the negative] = 3/2 - 30/12 = 3/2 - 5/2 [Find a common denominator for subtraction] = (3 - 5)/2 = -2/2 = -1

Therefore, 3/2 - (3/4 - 5/6) + (-2 7/12) simplifies to -1.
