Answer 2

To add these numbers, we need to convert the mixed numbers to improper fractions first:

4 6/1 = (4 * 1 + 6) / 1 = 10/1 -6 2/7 = (-6 * 7 + 2) / 7 = -44/7 -1 3/14 = (-1 * 14 + 3) / 14 = -11/14

Now we can add the fractions:

10/1 + (-44/7) + (-11/14)

To add fractions, we need to find a common denominator. The common denominator here is 1 * 7 * 14 = 98.

10/1 = (10 * 98) / (1 * 98) = 980/98 -44/7 = (44 * 14) / (7 * 14) = -616/98 -11/14 = (11 * 7) / (14 * 7) = -77/98

Now we can add the fractions:

980/98 + (-616/98) + (-77/98) = (980 - 616 - 77) / 98 = 287/98

The result is 287/98.
