To solve the expression -7 1/8 + 4 3/4, we need to follow these steps:

Step 1: Make sure that the fractions have the same denominator. In this case, the denominator will be 8 since it is the lowest common multiple of 8 and 4.

Step 2: Convert the mixed numbers into improper fractions. To do this, multiply the whole number by the denominator and add the numerator. For -7 1/8, the improper fraction is (-7 * 8 + 1) / 8 = -55 / 8. For 4 3/4, the improper fraction is (4 * 4 + 3) / 4 = 19 / 4.

Step 3: Add the two fractions by finding a common denominator, which is 8 in this case. The addition can be done by summing the numerators while keeping the denominator the same: (-55/8) + (19/4).

Step 4: To add the fractions, we need to have a common denominator. Since the denominator of the first fraction is already 8, we need to convert the denominator of the second fraction to 8 by multiplying both the numerator and denominator by 2: (-55/8) + (19 * 2 / 4 * 2) = (-55/8) + (38/8).

Step 5: Now that both fractions have the same denominator, combine the numerators: (-55 + 38) / 8 = -17/8.

The result of the expression -7 1/8 + 4 3/4 is -17/8.
