Answer 2

-2 + 1 7/8 = -2 + 1 + 7/8

First, add the whole numbers:

-2 + 1 = -1

Now, add the fractions:

-1 + 7/8

To add fractions with different denominators, you need to find a common denominator. In this case, the common denominator is 8:

-1 (which can be written as -8/8) + 7/8 = (-8/8) + 7/8

Now, you can add the fractions:

(-8/8) + 7/8 = (-8 + 7) / 8 = -1/8

So, -2 + 1 7/8 is equal to -1 1/8 when expressed as a mixed number, or -1.125 when expressed as a decimal.
