Need help with a fractions problem

For the question

"Juanita made two sandwiches. She cut the sandwiches into 4 pieces each. She has 5 pieces left. What fraction of the sandwiches are left?"

Shouldn't the answer be ^{5}/8? Yet in my math textbook it says the answer is 1 ^{1}⁄4. I've attached a scan of the textbook page.

It seems that both answers make sense, yet if that were true, then ^{5}/8 would equal to 1 ^{1}⁄4 but that is obviously not the case, so I'm really confused. Could someone explain to me which answer is correct? Thanks in advance!

Mixed number and Improper fractions

Improper fractions are when numerator is greater than denominator.........eg:5/4,9/7

Mixed number is a number consisting of a whole number and a proper fraction. eg: 1 1/4, 2 3/4

In your case Juanita has cut each sandwich to 4, if 5 pieces are left, then the mixed number is 1 and 1/4 sandwich is left or 5/4 sandwich is left ............it is not 5/8 left.

If Juanita cut each sandwich to 8 pieces each, and 10 pieces are left, then the mixed number or sandwich left is 1 and 2/8 or as improper fraction 10/8 .

If Juanita had cut each sandwich to 5 pieces each, and 8 pieces are left, then the sandwich left in terms of mixed number is 1 and 3/8 and as improper fraction it is 8/5.

If Juanita had cut each sandwich to 3 pieces each and 5 pieces are left, then the sandwich left in terms of mixed numbers is 1 and 2 /3 and improper fraction is 5/3.

Eg below:This is 1 and 3/4 as a mixed number. It can be written as 7/4 as a improper fraction so 1 and 3/4 pizzas are left or 7/4 pizzas are left....................its not 7/8.
