Question

three friends share a pizza divided into eighths if each person eats one slice how many more slices must be eaten so that one half of the pieces remains

Answer 1

If a pizza is divided into eights, that means that there are eight pieces of pizza. There are three people so if three people each eat one slice, that means there are five pieces of pizza left which is 5/8. 4/8 equals one half. So one more slice of pizza must be eaten for half of the pizza to remain.
