The correct option is A 8
Given that Alex ate 1 (1/7) of pizza.
Let’s convert it to an improper fraction.
Multiply 7 by 1 and add with the numerator 1, we get; 7 x 1 + 1 = 8.
The improper fraction is 8/7.
In improper fraction, the numerator should be the total number of slices eaten and the denominator should be slices having in one whole pizza.
Therefore, Alex had 8 slices of pizza.
