Answer 3

To solve the expression 3 1/6 + (-6 2/9 - 2 7/12), you can follow these steps:

Step 1: Convert all mixed numbers to improper fractions.

• 3 1/6 as an improper fraction is (3 * 6 + 1) / 6 = 19/6.
• -6 2/9 as an improper fraction is (-6 * 9 + 2) / 9 = -56/9.
• 2 7/12 as an improper fraction is (2 * 12 + 7) / 12 = 31/12.

So, the expression becomes: 19/6 + (-56/9) - (31/12).

Step 2: Find a common denominator for the fractions. The common denominator for 6, 9, and 12 is 36. So, we need to rewrite the fractions with this denominator:

• 19/6 becomes (19/6) * (6/6) = 114/36.
• -56/9 becomes (-56/9) * (4/4) = -224/36.
• 31/12 remains as it is.

Now, the expression is: 114/36 + (-224/36) - (31/12).

Step 3: Add and subtract the fractions.

• 114/36 + (-224/36) equals -110/36 (since you add the numerators when the denominators are the same).

• Now, subtract 31/12 from -110/36. To do this, find a common denominator for 36 and 12, which is also 36.

• 31/12 becomes (31/12) * (3/3) = 93/36.

Now, the expression is: -110/36 - 93/36.

Step 4: Combine the fractions:

• (-110/36) - (93/36) equals -203/36.

Step 5: Simplify the fraction (if needed):

• To simplify the fraction further, you can divide both the numerator and denominator by their greatest common divisor (GCD), which is 1 in this case.

So, the final result is: -203/36.

If you want to express this as a mixed number, you can divide -203 by 36:

-203 ÷ 36 = -5 with a remainder of 13.

So, the result as a mixed number is: -5 13/36.
