Suzy cut a loaf of bread into 25 pieces. after making sandwiches she had 5 pieces left. what fraction of the loaf of bread did she use to make sandwiches

First we need to findustries out how many bread pieces were used. 25-5=20 pieces used. This means the fraction of bread used is 20/25, but that is not the simplified fraction. 20/25 5 5 =4/5 She used 4/5 of the loaf to make sandwiches.

20
 Hope that helped:)
