Answer 3

To calculate the expression "3 1/2 - 2 5/2 + 5/6 - 1," you can start by simplifying each part of the expression individually and then combining the results.

1. Convert the mixed numbers to improper fractions:

   • 3 1/2 = 7/2
   • 2 5/2 = 9/2

2. Rewrite the expression: (7/2) - (9/2) + (5/6) - 1

3. Now, find a common denominator for all the fractions. The least common multiple of 2 and 6 is 6.

4. Rewrite each fraction with a denominator of 6: (7/2) becomes (21/6) (9/2) becomes (27/6) (5/6) remains (5/6)

5. Now the expression looks like this: (21/6) - (27/6) + (5/6) - 1

6. Combine the fractions with a common denominator: (21/6 - 27/6 + 5/6) - 1

7. Perform the arithmetic within the parentheses: (21 - 27 + 5)/6 - 1

8. Further simplify the numerator: (-1/6) - 1

9. Combine the two fractions with different denominators: To do this, you need to have a common denominator. The common denominator for 6 and 1 is 6. So, convert 1 to a fraction with a denominator of 6: -1/6 - 6/6

10. Combine the fractions: (-1/6) - (6/6) = (-1/6 - 6/6)

11. Perform the subtraction: -1/6 - 6/6 = -7/6

So, the final result is -7/6.
