Answer 3

To add the mixed numbers 2 1/6 and -17 1/4, we can first convert them to improper fractions.

2 1/6 is equivalent to (2 * 6 + 1)/6 = 13/6.

-17 1/4 is equivalent to (-17 * 4 + 1)/4 = -69/4.

Now, we can add the fractions:

13/6 + (-69/4) = (13 * 4 + (-69 * 6))/(6 * 4) = (52 - 414)/24 = -362/24.

To simplify the fraction, we can divide both the numerator and the denominator by their greatest common divisor, which is 2:

-362/24 = (-362 ÷ 2)/(24 ÷ 2) = -181/12.

Now, let's convert the improper fraction back to a mixed number:

-181/12 = -15 1/12.

Therefore, the sum of 2 1/6 and -17 1/4, when simplified, is -15 1/12.
